3 Description
The LP5912-Q1 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-
Q1 device provides low noise, high PSRR, low
quiescent current, and low line and load transient
response. The LP5912-Q1 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.
