LD59015
150 mA low noise high PSRR linear voltage regulator
Datasheet - production data
Description
SOT323-5L
Features
• Input voltage from 2.4 to 5.5 V
• Very low quiescent current (31 µA typ. at noload, 75 µA typ. at 150 mA load, 1 µA max. in
OFF mode)
• Very low noise (20 µVRMS at VOUT = 1.5 V)
The LD59015 provides 150 mA maximum current
with an input voltage range from 2.4 V to 5.5 V,
and a typical dropout voltage of 150 mV. It is
stable with ceramic capacitors. High PSRR, low
quiescent current and low noise features make it
suitable for low power battery-powered
applications. Power supply rejection is 80 dB at
low frequency and starts to roll off at 10 kHz. The
enable logic control function puts the LD59015 in
shutdown mode, allowing a total current
consumption lower than 1 µA. The device also
includes short-circuit constant current limiting and
thermal protection. Typical applications are
mobile phones, personal digital assistants
(PDAs), cordless phones and similar batterypowered systems.
• Output voltage tolerance: ± 1.8% at 25 °C
• 150 mA guaranteed output current
• Wide range of output voltages available on
request: 1.2 V to 3.3 V in 100 mV steps
• Logic-controlled electronic shutdown
• Compatible with ceramic capacitors
• Very high PSRR (80 dB @ 100 Hz, 76 @
10 kHz, 54 @ 100 kHz)
• Internal current and thermal limit
• Package: SOT323-5L
• Temperature range: -40 °C to 125 °C

1. For VOUT(NOM) < 1.3 V, VIN = 2.4 V.
2. Dropout voltage is the input-to-output voltage difference at which the output voltage is 100 mV below its nominal value. This
specification does not apply to output voltages below 1.7 V.
3. Turn-on time is time measured between the enable input just exceeding VEN high value and the output voltage just
reaching 95% of its nominal value.
