SNVS539H – NOVEMBER 2007 – REVISED SEPTEMBER 2015 LP3850x-ADJ, LP3850xA-ADJ 1.5-A Flexcap Low-Dropout Linear Regulator
for 2.7-V to 5.5-V Inputs
1 Features 3 Description TI's FlexCap low-dropout (LDO) linear regulators
feature unique compensation that allow use of any
type of output capacitor with no limits on minimum or
maximum equivalent series resistance (ESR). The
LP38500 and LP38502 series of LDOs operates from
a 2.7-V to 5.5-V input supply. These ultra-low-dropout
linear regulators respond very quickly to step
changes in load, making them suitable for low-voltage
microprocessor applications. Developed on a CMOS
process (utilizing a PMOS pass transistor) the
LP38500-ADJ and LP38502-ADJ have low quiescent
currents that changes little with load current. GND Pin Current: Typically 2 mA at 1.5-A load
current. Disable Mode: Typically 25-nA quiescent current
when the EN pin is pulled low. (LP38502-ADJ) Simplified Compensation: Stable with any type of
output capacitor, regardless of ESR. Precision Output: A grade versions available with …
