General Description

The LP5900 is a linear regulator capable of supplying 150 mA output current. Designed to meet the requirements of RF/Analog circuits, the LP5900 device provides low noise, high PSRR, low quiescent current, and low line transient response figures. Using new innovative design techniques the LP5900 offers class-leading device noise performance without a noise bypass capacitor.

The device is designed to work with 0.47 μF input and output ceramic capacitors. (No Bypass Capacitor is required)

The device is available in micro SMD package and LLP package. For all other package options contact your local NSC sales office.

This device is available with 1.5V,1.575V, 1.8V, 1.9V, 2.0V, 2.1V, 2.2V, 2.3V, 2.5V, 2.6V, 2.7V, 2.75V 2.8V, 2.85V 3.0V, and 3.3V outputs. Please contact your local sales office for any other voltage options.
