KR32S018M/F~KR32S033M/F

BIPOLAR LINEAR INTEGRATED CIRCUIT

Revision No : 0

300

POWER 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%

Very low ground current : 1.8
