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.
