HIGH RIPPLE-REJECTION SOFT-START FUNCTION
CMOS VOLTAGE REGULATOR
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 F
small ceramic capacitor can be used. It operates with low current consumption of 36 A typ. Furthermore the overcurrent
protection circuit prevents the load current from exceeding the capacity of output transistor.
SOT-23-5, SC-82AB and super small HSNT-4 (1010) packages realize high-density mounting.

80 dB typ. (f = 1.0 kHz)
The rising time of output voltage immediately after power-on or after the
ON / OFF pin is set to ON is adjustable.
The soft-start time of SOT-23-5 can be switched to tSS0 = 0.1 ms typ. /
tSS1 = 1.0 ms typ. with the SST pin.
The soft-start time of SC-82AB is fixed to tSS0 = 0.1 ms typ.
The soft-start time of HSNT-4 (1010) is fixed to either tSS0 = 0.1 ms typ.
or tSS1 = 1.0 ms typ.
Limits overcurrent of output transistor.
Ensures long battery life.
