LP5912-1.2DRVR

The LP5912 is low-noise LDO that can supply up to
500 mA of output current. Designed to meet the
requirements of RF and analog circuits, the LP5912
device provides low noise, high PSRR, low quiescent
current, and low line and load transient response.
The LP5912 offers class-leading noise performance
without a noise bypass capacitor and with the ability
for remote output capacitance placement.
The device is designed to work with a 1-µF input and
a 1-µF output ceramic capacitor (no separate noise
bypass capacitor required).
This device is available with fixed output voltages
from 0.8 V to 5.5 V in 25-mV steps. Contact Texas
Instruments Sales for specific voltage option needs.
