S5225M

Semiconductor S52xxM Low Drop Output Voltage Regulator Description The S52xxM is a u-cap 150mA linear voltage regulator in the SOT-25 package. This regulator has very low dropout voltage and very low ground current. It is designed especially for hand-sets, battery-powered devices and can be controlled by a CMOS or TTL. When the S52xxM is disabled, power consumption drops to nearly zero. Features • Output current of 150 ㎃ • Low quiescent current • Low dropout voltage • Current limit protection • Logic-controlled electronic enable Ordering Information Type NO.

Parts are tested for load regulation in the load range from 0.1 ㎃ to 150 ㎃. Note 4 : Quiescent current is the regulator standby current plus pass transistor base current. The total current drawn from the supply is the sum of the load current plus the quiescent current. Note 5 : Dropout voltage is defined as the input to output differential at which the output voltage Drops 2% below its nominal value measured at 1V differential.
