Overview

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 microF input and output ceramic capacitors. (No Bypass Capacitor is required). The device is available in micro SMD package and LLP package. This device is available with 1.5V, 1.8V, 2.0V, 2.2V, 2.5V, 2.7V, 2.8V, 3.0V, and 3.3V outputs. This evaluation board is designed to enable the evaluation of the LP5900 Voltage Regulator. each board is assembled and tested in the factory. This evaluation board has the microSMD-4 bump package mounted.
