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.

Note 3 : Regulation is measured at constant junction temperature using low duty cycle pulse testing.
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.
