DESCRIPTION

The LP5907 is a linear regulator capable of supplying 250-mA output current. Designed to meet the requirements

of RF and analog circuits, the LP5907 device provides low noise, high PSRR, low quiescent current, and low line

or load transient response figures. Using new 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 1-µF input and a 1-µF output ceramic capacitor (no bypass capacitor is

required).

The device is available in an ultra-thin micro SMD package as well as a 5-pin SOT23 package. This device is

available between 1.2 V and 4.5 V in 25-mV steps. Please contact Texas Instruments Sales for specific voltage

option needs.
