S-1335 Series 5.5 V INPUT, 150 mA VOLTAGE REGULATOR www.ablic.com WITH SOFT-START FUNCTION ABLIC Inc., 2012-2019 Rev.1.4 00 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. Features Output voltage: 1.0 V to 3.6 V, selectable in 0.05 V step 1.5 V to 5.5 V Input voltage: Output voltage accuracy: 1.0% (1.0 V to 1.45 V output product: 15 mV) Dropout voltage: 70 mV typ. (2.8 V output product, IOUT = 100 mA) Current consumption: During operation: 36 A typ., 54 A max. During power-off: 0.1 A typ., 1.0 A max. *1 Output current: Possible to output 150 mA (VIN VOUT(S) + 1.0 V) Input and output capacitors: A ceramic capacitor of 1.0 F or more can be used. Ripple rejection: 70 dB typ. (f = 10 kHz, VOUT(S) 2.5 V) 80 dB typ. (f = 1.0 kHz) Built-in soft-start circuit: 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. Built-in overcurrent protection circuit: Limits overcurrent of output transistor. Built-in ON / OFF circuit: Ensures long battery life. Discharge shunt functionavailabl /unavailabl is selectable. Pull-down functionavailabl /unavailabl is selectable. Operation temperature range: Ta = 40C to +85C Lead-free (Sn 100%), halogen-free *1. Attention should be paid to the power dissipation of the package when the output current is large.
