S5250M

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 150mA • Low quiescent current • Low dropout voltage • Current limit protection • Logic-controlled electronic enable Pin Connections 5 4 1 2 PIN Connections 1. Input 2. Ground 3. Control 4. Noise bypass 5. Output 3 Ordering Information Type NO.
