S-1142C/D Series HIGH-WITHSTAND VOLTAGE LOW CURRENT CONSUMPTION LOW DROPOUT CMOS VOLTAGE REGULATOR www.sii-ic.com SII Semiconductor Corporation, 2012-2014 Rev.1.2 01 The S-1142C/D Series, developed by using high-withstand voltage CMOS technology, is a positive voltage regulator with a high-withstand voltage, low current consumption, and high-accuracy output voltage. The S-1142C/D Series operates at a high maximum operating voltage of 50 V and a low current consumption of 4.0 A typ. In addition to a built-in low on-resistance transistor which provides a very small dropout voltage and a large output current, this voltage regulator also has a built-in ON / OFF circuit. An overcurrent protection circuit prevents the load current from exceeding the capacitance of the output transistor, and a built-in thermal shutdown circuit prevents damage caused by heat. A high heat radiation HSOP-6 package enables high-density mounting. Features Output voltage: 2.0 V to 15.0 V, selectable in 0.1 V step Input voltage: 3.0 V to 50 V Output voltage accuracy: 1.0% (Tj = +25C) 3.0% (Tj = 40C to +105C) Current consumption: During operation: 4.0 A typ., 9.0 A max. (Ta = 40C to +85C) During power-off: 0.1 A typ., 1.0 A max. (Ta = 40C to +85C) *1 Output current: Possible to output 200 mA (V V + 2.0 V) IN OUT(S) Input and output capacitors: A ceramic capacitor of 0.1 F or more can be used. Built-in overcurrent protection circuit: Limits overcurrent of output transistor. Built-in thermal shutdown circuit: Prevents damage caused by heat. Built-in ON / OFF circuit: Ensures long battery life. 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.
