3 Description
The LP5907-Q1 is a linear regulator capable of
supplying 250-mA output current. Designed to meet
the requirements of RF and analog circuits, the
LP5907-Q1 device 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 1.20 V to 4.50 V in 25-mV steps. Contact Texas
Instruments Sales for specific voltage option needs.
