LP5900SD-3.3

• Product Introduction

The LP5900 linear regulator is capable of delivering 150mA of output current. The LP5900 device is designed to meet the requirements of RF/analog circuits, providing low noise, high PSRR, low quiescent current, and low line transient response digital. Using new innovative design technology, the LP5900 delivers class-leading device noise performance in noise-free bypass capacitors. The device is designed to work with 0.47μF input and output ceramic capacitors down to the size of 0603 components.

The device is available in a micro SMD package and an LLP package. This device is available with 1.5V, 1.8V, 2.0V, 2.2V, 2.5V, 2.6V, 2.7V, 2.8V, 3.0V, and 3.3V outputs.

The purpose of this evaluation board is to enable the evaluation of the LP5900 voltage regulator. Each board is assembled and tested in the factory. The EV kit is fitted in a 6-pin LLP package.
