LP8358 150mA, µCap, Low Dropout Voltage Regulator with Power Good
February 2003
LP8358
150mA, µCap, Low Dropout Voltage Regulator with
Power Good
General Description
The LP8358 is a µCap, precise CMOS voltage regulator with
low Power good output R
DSON
.
It provides up to 150mA and consumes a typical of 10nA in
shutdown mode. The LP8358 output stage is designed with
a push pull output for faster transient recovery response.
The LP8358 is optimized to work with low value, low cost
ceramic capacitors. The output typically require only 1µF of
output capacitance for stability. The enable pin can be tied to
V
IN
for easy board layout.
The LP8358 is designed for portable, battery powered equip-
ment applications with small space requirements.
The LP8358 is available in a 5-pin SOT-23 package. Perfor-
mance is specified for the −40˚C to +125˚C temperature
range and is available in a fixed 1.2V. For other output
voltage options, please contact National Semiconductor.
