S-1212B/D Series 105C OPERATION, www.ablic.com 36 V INPUT, 250 mA VOLTAGE REGULATOR ABLIC Inc., 2015-2018 Rev.3.1 00 The S-1212B/D Series, developed by using high-withstand voltage CMOS process technology, is a positive voltage regulator with a high-withstand voltage, low current consumption and high-accuracy output voltage, and has a built-in ON / OFF circuit. The S-1212B/D Series operates at the maximum operation voltage of 36 V and a low current consumption of 6.5 A typ., and has a built-in low on-resistance output transistor which provides a very small dropout voltage and a large output current. Also, a built-in overcurrent protection circuit to limit overcurrent of the output transistor and a built-in thermal shutdown circuit to limit heat are included. Features Output voltage: 2.5 V to 16.0 V, selectable in 0.1 V step Input voltage: 3.0 V to 36 V Output voltage accuracy: 2.0% (Ta = +25C) Current consumption: During operation: 6.5 A typ. (Ta = +25C) During power-off: 0.1 A typ. (Ta = +25C) *1 Output current: Possible to output 250 mA (at V V + 2.0 V) IN OUT(S) Input capacitor: A ceramic capacitor can be used. (1.0 F or more) Output capacitor: A ceramic capacitor can be used. (1.0 F to 100 F) Built-in overcurrent protection circuit: Limits overcurrent of output transistor. Built-in thermal shutdown circuit: Detection temperature 165C typ. Built-in ON / OFF circuit: Ensures long battery life. Discharge shunt function is available. Operation temperature range: Ta = 40C to +105C Lead-free (Sn 100%), halogen-free *1. Please make sure that the loss of the IC will not exceed the power dissipation when the output current is large.
