LP2983
Micropower 150 mA Voltage Regulator in SOT-23
Package For Output Voltages ≤ 1.2V
Designed for Use with Very Low ESR Output Capacitors
General Description
The LP2983 is a 150 mA, fixed-output voltage regulator
designed to provide tight voltage regulation in applications
with output voltages ≤ 1.2V.
Using an optimized VIP™ (Vertically Integrated PNP) pro-
cess, the LP2983 delivers unequalled performance in all
critical specifications:
Ground Pin Current: Typically 825 µA @ 150 mA load, and
75 µA @ 1 mA load.
Enhanced Stability: The LP2983 is stable with output ca-
pacitor ESR down to zero, which allows the use of ceramic
capacitors on the output.
Smallest Possible Size: SOT-23 package uses absolute
minimum board space.
Precision Output: 1% tolerance output voltages available
(A grade).
