CS52015-3
1.5 A, 3.3 V Fixed Linear
Regulator
The CS52015–3 linear regulator provides 1.5 A @ 3.3 V reference
at 1.0 A with an output voltage accuracy of ±1.5 %.
The 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 operate with dropout voltages less than 1.4 V
at 1.5 A output current. The maximum quiescent current is only 10 mA
at full load. Device protection includes over–current and thermal
shutdown.
