S-1142

Rev.1.0_03 HIGH-WITHSTAND VOLTAGE LOW CURRENT CONSUMPTION LOW DROPOUT CMOS VOLTAGE REGULATOR S-1142 Series The S-1142 Series, developed based on high-withstand voltage CMOS process, is a positive voltage regulator with a high-withstand voltage, low current consumption, and high output voltage accuracy. The S-1142 Series operates at a high maximum operating voltage of 50 V and a low current consumption of 4.0 µA (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 power-off circuit. An overcurrent protector prevents the load current from exceeding the capacitance of the output transistor. 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 12.0 V, selectable in 0.1 V step Low equivalent series resistance capacitor : Ceramic capacitor of 0.1 µF or more can be used as the I/O capacitor. Input voltage : 3.0 V to 50 V High-accuracy output voltage : ±1.0% (at Tj = +25°C), ±3.0% (Tj = −40°C to +105°C) Low current consumption : During operation: 4.0 µA typ., 9.0 µA max. (Tj = −40°C to +105°C) During shutdown: 0.1 µA typ., 1.0 µA max. (Tj = −40°C to +105°C) Output current : 200 mA (at VIN ≥ VOUT(S) + 2.0 V)*1 Built-in overcurrent protector : limits overcurrent of output transistor Operation temperature range : −40°C to +105...
