KR52S018M Datasheet, PDF (1/5 Pages) KEC(Korea Electronics) – BIPOLAR LINEAR INTEGRATED CIRCUIT
SEMICONDUCTOR
TECHNICAL DATA
500mA POWER LOW DROPOUT REGULATOR
The KR52SXXXM/F is an efficient linear voltage regulator with very low
dropout voltage(Typically 10mV at light loads and 350mV at 500mA)
The KR52SXXXM/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%
