Seiko: Positive Voltage Regulator IC

High Ripple-Rejection Soft-Start Function CMOS Voltage Regulator S-1335 Series

 March 29, 2013

The S-1335 Series, developed by using the CMOS technology, is a positive voltage regulator IC of 150 mA output current, which has low dropout voltage, high-accuracy output voltage and soft-start function.

The rising time of output voltage immediately after power-on or after the ON / OFF pin is set to ON is adjustable. A 1.0 µF small ceramic capacitor can be used. It operates with low current consumption of 36 µA typ. Furthermore the overcurrent protection circuit prevents the load current from exceeding the capacitance of output transistor.

SOT-23-5, SC-82AB and super small HSNT-4 (1010) packages realize high-density mounting.

 


*1. Attention should be paid to the power dissipation of the package when the output current is large.
