DescriptionThe LP5900is an LDO capableof supplying 150-mA
output current. Designedto meet the requirementsof 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 withouta noise bypass
capacitor.
The deviceis designedto work with 0.47-μF input
and output ceramic capacitors (no bypass capacitor
required).
The deviceis availableina DSBGA (YZR) package
anda WSON package; the deviceis also availablein extremely thin DSBGA (YPF) package. For all
voltage and package options available today, see the
Package Option Addendum (POA)at the endof this
data sheet. For any other fixed output voltages from
1.5Vto 4.5Vin 25-mV steps andall other package
options, contact your localTI Sales office.
Device Information(1)(1) Forall available packages, see the orderable addendumat
