SEMICONDUCTOR TECHNICAL DATA 300 POWER LOW DROPOUT REGULATOR KR32S018M/F~KR32S033M/F BIPOLAR LINEAR INTEGRATED CIRCUIT 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 G 1 E B 5 DIM MILLIMETERS _ A 2.9 + 0.2 B C 1.6+0.2/-0.1 _ 0.70 + 0.05 _ 0.4 + 0.1 2.8+0.2/-0.3 _ 1.9 + 0.2 0.95 _ 0.16 + 0.05 0.00-0.10 0.25+0.25/-0.15 0.60 0.55 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 A F 2 D 4 D E F G H I J K L G 3 C 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 J 1.
