3 Description

The LP5900 is an LDO capable of supplying 150-mA

output current. Designed to meet the requirements of

RF and 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; the device is also available in

an extremely thin DSBGA (YPF) package. For all

voltage and package options available today, see the

Package Option Addendum (POA) at the end of this

data sheet. For any other fixed output voltages from

1.5 V to 4.5 V in 25-mV steps and all other package

options, contact your local TI Sales office.
