WR0332-12A50R

WR0332 High PSRR, High speed, CMOS LDO General Description Features The WR0332 series is a high accuracy, low noise, ⚫ Input Voltage: 2.0V~5.5V high speed, low dropout CMOS Linear regulator with ⚫ Output Voltage: 1.0V~3.3V high ripple rejection. The devices offer a new level of ⚫ Output Current: 300mA cost-effective performance in cellular phones, laptop ⚫ PSRR: 70dB@1KHz and notebook computers, and other portable devices. ⚫ Dropout Voltage: 220mV @ IOUT = 300mA ⚫ Operating Temperature: -40~+125ºC ⚫ Shut-down Current: < 1μA ⚫ Quiescent Current: 60μA Typ. ⚫ Recommend Capacitor: 1μF The WR0332 has the fold-back maximum output current which depends on the output voltage. So the current limit functions both as a short circuit protection and as an output current limiter. Applications The WR0332 regulators are available in standard SOT23-3 package、SOT23-5 package and DFN1x14 Package. Standard products are Pb-free and Halogen-free. ⚫ MP3/MP4 Players ⚫ Cellphones, radiophone, digital cameras ⚫ Bluetooth, wireless handsets ⚫ Others portable electronic device Typical Application W02040004 – Rev1.5 www.way-on.com 1 WR0332 Pin Configuration (Top View) 5 3 1 1 2 SOT23-3 2 4 4 3 3 1 2 SOT23-5 DFN-4 Pin Description Pin Number Pin Description SOT23-3 SOT23-5 DFN-4 Name 3 1 4 IN Input Voltage 1 2 2 GND Ground - 3 3 EN Enable, Active High - 4 - NC NC 2 5 1 OUT Output Voltage - EPAD Exposed pad should be connected directly to the GND pin.

VDO is measured for devices with VOUT(nom) ≥ 1.8 V. Note2: Maximum output current is affected by the PCB layout, size of metal trace, the thermal conduction path between metal layers, ambient temperature and the other environment factors of system. Attention should be paid to the dropout voltage when VIN < VOUT + VDROP. Note3: The Load regulation is measured using pulse techniques with duty cycle < 5%. www.way-on.com March 2021 – Rev1.5 4 WR0332 Typical Characteristics (Ta=25ºC, VIN=VOUT+1V, CIN=COUT=1µF, unless otherwise noted) Quiescent Current vs. Supply Voltage Quiescent Current vs. Supply Voltage Output Voltage vs. Supply Voltage Output Voltage vs. Supply Voltage Output Voltage vs. Output Current Output Voltage vs. Output Current March 2021 – Rev1.5 www.way-on.com 5 WR0332 Quiescent Current vs. Temperature Output Voltage vs. Temperature Dropout Voltage vs. Output Current Power Supply Rejection Ratio vs. Frequency www.way-on.com March 2021 – Rev1.5 6 WR0332 Soft Start from EN EN Shutdown Soft Start from EN EN Shutdown Line Transient Load Transient Line Transient Load Transient March 2021 – Rev1.5 www.way-on.com 7 WR0332 Block Diagram OUT IN Current Limit VREF EN Enable Control OTP GND www.way-on.com March 2021 – Rev1.5 8 WR0332 Package Information SOT 23-3 SYMBOL DIMENSIONS IN MILLIMETERS MIN NOM MAX A 2.60 2.80 3.00 A1 1.50 1.60 1.70 B 0.95BSC C 0.25 0.40 0.50 D 2.82 2.92 3.02 E 0.10 0.15 0.20 L 0.59REF L1 0.30 0.45 0.60 F1 0.90 1.10 1.30 F 0.00 0.08 0.15 March 2021 – Rev1.5 www.way-on.com 9 WR0332 SOT 23-5 SYMBOL DIMENSIONS IN MILLIMETERS MIN NOM MAX A 2.60 2.80 3.00 A1 1.50 1.60 1.70 B 0.95BSC B1 1.90BSC C 0.25 0.40 0.50 D 2.82 2.92 3.02 E 0.10 0.15 0.20 F 0.00 0.08 0.15 L 0.59REF F1 0.90 1.10 1.30 L1 0.30 0.45 0.60 www.way-on.com March 2021 – Rev1.5 10 WR0332 A E D C DETAIL A Pin 1 ID and Tie Bar Mark Options F Pin1 Note: The configuration of the Pin 1 identifier Top View Bottom View is optional, but must be located within the zone indicated.
