3 Description
The LP5907 is a low-noise LDO that can supply
up to 250mA output current. Designed to meet the
requirements of RF and analog circuits, the LP5907
provides low noise, high PSRR, low quiescent current,
and low line or load transient response figures. Using
innovative design techniques, the LP5907 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 1μF input and
a 1μF output ceramic capacitor (no separate noise
bypass capacitor is required).
This device is available with fixed output voltages
from 1.2V to 4.5V in 25mV steps. Contact Texas
Instruments Sales for specific voltage option needs.
