3 Description
The LP5907-Q1 is a low-noise LDO that can supply
250 mA of output current. Designed to meet the
requirements of RF and analog circuits, the LP5907-
Q1 provides low noise, high PSRR, low quiescent
current, and low line or load transient response
figures. Using new innovative design techniques, the
LP5907-Q1 offers class-leading noise performance
without a noise bypass capacitor and the ability for
remote output capacitor placement.
The device is designed to work with a 1-μF input and
a 1-μF output ceramic capacitor (no separate noise
bypass capacitor is required).
This device is available with fixed output voltages
from 1.2 V to 4.5 V in 25-mV steps. Contact Texas
Instruments Sales for specific voltage option needs.
