CS5203−3
3.0 A, 3.3 V Fixed Linear
Regulator
The CS5203−3 linear regulator provides 3.3 V reference at 3.0 A
with an output voltage accuracy of ±1.5%.
This regulator is intended for use as a post regulator and
microprocessor supply. The fast loop response and low dropout
voltage make this regulator ideal for applications where low voltage
operation and good transient response are important.
The circuit is designed to provide 3.0 A of output current with
dropout voltages of less than 1.15 V. The maximum quiescent current
is only 10 mA at full load. Device protection includes over−current
and thermal shutdown.
The CS5203−3 is pin compatible with the LT1085 family of linear
regulators.
The regulator is available in a surface mount D²PAK−3 package.
