TECHNICAL DATAKR32S018M/F~KR32S033M/F

BIPOLAR LINEAR INTEGRATED CIRCUIT

Revision No : 0300POWER LOW DROPOUT REGULATOR

The KR32SXXXM/F is an efficient linear voltage regulator with very low

dropout voltage (Typically 10mV at light loads and 250mV at 300)

The KR32SXXXM/F can be enabled, or shut down by a CMOS or TTL

compatible signal. When disabled. power consumption drops nearly to zero.

Dropout ground current is minimized to help prolong battery life. Other key

features include reversed battery protechion, current limiting, over temperature

shutdown, and low noise performance with an ultra-low-noise option

FEATURES

High output voltage accuracy : 1%

Low quiescent current. : IQ(OFF)=3

Very low ground current : 1.8(IOUT=150)

Low dropout voltage : 250mV (IOUT=300)

Built-in ON/OFF control terminal

Built -in over current , Over heat protection function

Reverse-battery protection

APPLICATIONS

Laptop, notebook, and palmtop computers

Cellular telephones and battery-powered equipment

Consumer and personal electronics

PC Card VCCand VPP regulation and switching
