产品说明

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 required).

The device is available in a DSBGA (YZR) package and a WSON package; also available in an extremely thin DSBGA (YPF) package. For all other package options, contact your local Texas Instruments sales office.

This device is available with 1.5-V, 1.575-V, 1.8-V, 1.9-V, 2-V, 2.1-V, 2.2-V, 2.3-V, 2.5-V, 2.6-V, 2.65-V, 2.7-V, 2.75-V 2.8-V, 2.85-V 3-V, 3.3-V and 4.5-V outputs. Please contact your local sales office for any other voltage options.
