CS52015-1
CS52015-1
1.5A Adjustable Linear Regulator
Description
The CS52015-1 linear regulator pro-
vides 1.5A with an accuracy of ±1%.
The device uses two external resis-
tors to set the output voltage within
a 1.25V to 5.5V range.
The regulator is intended for use as
a post regulator and microprocessor
supply. The fast loop response and
low dropout voltage make this reg-
ulator ideal for applications where
low voltage operation and good
transient response are important.
The circuit is designed to operate
with dropout voltages less than
1.4V at 1.5A output current. Device
protection includes overcurrent and
thermal shutdown.
The CS52015-1 is pin compatible
with the LT1086 family of linear
regulators but has lower dropout
voltage.
The regulator is available in TO-
220, surface mount D
2
, and SOT-223
packages.
