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.

Features

• Output Current to 3.0 A

• Output Accuracy to ±1.5% Over Temperature

• Dropout Voltage (typical) 1.15 V @ 3.0 A

• Fast Transient Response

• Fault Protection
