LP5900SD-1.8/NOPB

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.
