Functional Block Diagram
Input
Iadj
This regulator offers full overload protection available
only in integrated circuits. Included on the chip are
current-limiting and thermal-overload protection. All
overload-protection circuitry remains fully functional,
even when ADJUSTMENT is disconnected. Normally,
no capacitors are required unless the device is
situated far from the input filter capacitors, in which
case an input bypass is required. An optional output
capacitor can be added to improve transient
response. ADJUSTMENT can be bypassed to
achieve very high ripple rejection.
In addition to replacing fixed regulators, the TL317
regulator is useful in a wide variety of other
applications. Because the regulator is floating and
sees only the input-to-output differential voltage,
supplies of several hundred volts can be regulated as
long as the maximum input-to-output differential is not
exceeded. Its primary application is that of a
programmable output regulator, but by connecting a
fixed resistor between ADJUSTMENT and OUTPUT,
this device can be used as a precision current
regulator. Supplies with electronic shutdown can be
achieved by clamping ADJUSTMENT to ground,
programming the output to 1.25 V, where most loads
draw little current.

7 Detailed Description
7.1 Overview
The TL317 device is an adjustable three-terminal positive-voltage regulator capable of supplying up to 100 mA
over an output-voltage range of 1.25 V to 32 V. It requires only two external resistors to set the output voltage.
The TL317 device is versatile in its applications, including uses in programmable output regulation and local oncard regulation. Also, by connecting a fixed resistor between the ADJUSTMENT and OUTPUT terminals, the
TL317 device can function as a precision current regulator. An optional output capacitor can be added to improve
transient response. The ADJUSTMENT terminal can be bypassed to achieve very high ripple-rejection ratios,
which are difficult to achieve with standard three-terminal regulators.

7.3 Feature Description
7.3.1 NPN Darlington Output Drive
NPN Darlington output topology provides naturally low output impedance and an output capacitor is optional.
7.3.2 Programmable Feedback
An internal amplifier with 1.25-V offset input at the ADJUSTMENT terminal provides easy output voltage or
current (not both) programming. For current regulation applications, a single resistor whose resistance value is
1.25 V / IO and power rating is greater than (1.25 V)2 / R must be used. For voltage regulation applications, two
resistors set the output voltage as described in Adjustable Voltage Regulator.
7.4 Device Functional Modes
7.4.1 Normal Operation
The device OUTPUT pin sources current necessary to make the OUTPUT pin 1.25 V greater than the
ADJUSTMENT pin to provide output regulation
7.4.2 Operation With Low Input Voltage
The device requires 2.5 V of headroom (VI – VO) to regulate the OUTPUT. With less headroom, the OUTPUT
voltage of the device may be below the desired setpoint.
7.4.3 Operation in Light Loads
The device passes its bias current to the OUTPUT pin. The load or feedback must consume this minimum
current for regulation or the output may be too high. The minimum current require to regulate is provided in the
Electrical Characteristics, so the series resistance used to set the output voltage is recommended to be VO / IMIN
to ensure regulation at all times.

8 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
The flexibility of the TL317 allows it to be configured to take on many different functions in DC power
applications.

8.2.1.1 Design Requirements
•
•
•
R1 and R2 are required to set the output voltage.
C1 is recommended, particularly if the regulator is not in close proximity to the power-supply filter capacitors.
A 0.1-µF ceramic or 1-µF tantalum capacitor provides sufficient bypassing for most applications, especially
when adjustment and output capacitors are used.
Use of an output capacitor, C2, improves transient response, but is optional.
8.2.1.2 Detailed Design Procedure
VO is calculated as shown in Equation 1. IADJ is typically 50 µA and negligible in most applications.
Power dissipation for linear regulators is calculated as shown in Equation 2. IADJ is typically 50 µA and negligible
in most applications, so a typical way to calculate power dissipation for linear regulators is simplified to
Equation 3.
VO = VREF (1 + R2 / R1) + (IADJ × R2)
P = (VI - VO) × IO + (VI - VADJ) × IADJ
P = (VI - VO) × IO

8.2.6 Slow-Turnon 15-V Regulator Circuit
The capacitor C1, in combination with the PNP transistor, helps the circuit to slowly start supplying voltage. In the
beginning, the capacitor is not charged. Therefore, output voltage starts at VC1+ VBE + 1.25 V = 0 V + 0.65 V +
1.25 V = 1.9 V. As the capacitor voltage rises, VOUT also rises at the same rate. When the output voltage reaches
the value determined by R1 and R2, the PNP is turned off.

The current limit operation mode can be used to trickle charge a battery at a fixed current. ICHG = 1.25 V / 24 Ω.
VI must be greater than VBAT + 4.25 V (1.25 V [VREF] + 3 V [headroom]).
Power dissipation through resistor R1 is calculated as shown in Equation 5, so a resistor with the appropriate
power rating must be chosen for this application.

9 Power Supply Recommendations
The TL317 is designed to operate from an input voltage supply range between 1.25 V to 35 V greater than the
output voltage. If the device is more than six inches from the input filter capacitors, an input bypass capacitor,
0.1-µF (or greater), of any type is required for stability.
10 Layout
10.1 Layout Guidelines
•
•
•
It is recommended that the input terminal be bypassed to ground with a bypass capacitor.
The optimum placement for the bypass capacitor is closest to the input terminal of the device and the system
GND. Take care to minimize the loop area formed by the bypass-capacitor connection, the input terminal, and
the system GND.
For operation at full rated load, it is recommended to use wide trace lengths to eliminate I × R drop and heat
dissipation.

11.4 Electrostatic Discharge Caution
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
