Rev.1.0 HIGH OPERATING VOLTAGE CMOS VOLTAGE REGULATOR S-812C Series The S-812C series is a family of high-voltage positive regulators developed using CMOS technology. The maximum operating voltage of 16V makes the S-812C series best in high-voltage applications. Not only current consumption is small but also power-off function is included, the regulator is also suitable in constructing lowpower portable devices. bination of power-off function and short-current protection can be selected. - Features - Low current consumption - Power source for battery-powered devices Operating current: Typ. 1.0 µA, Max. 1.8 µA (3.0 V) - Power source for personal munication - Output voltage: 2.0 to 6.0 V (0.1 V step) devices - Output voltage accuracy: ±2.0% - Power source for home electric/electronic - Output current: appliances Note1 50m A capable (3.0 V output product, VIN=5 V) Note1 75m A capable (5.0 V output product, VIN=7 V) - Dropout voltage Typ. 120 m V (VOUT = 5.0 V, IOUT = 10 m A) - Power-off function: Polarity for power-off switch or removal of the power-off function can be selected. - Short-circuit protection: Product with/without short-circuit protection is available. Short-circuited current : 40 m A typ. for products with protection - Packages: SOT-23-5 (Package drawing code : MP005-A) SOT-89-5 (Package drawing code : UP003-A) SOT-89-3 (Package drawing code : UP005-A) TO-92 (Package drawing code : YF003-A) Note1 Power dissipation of the package should be taken into account when the output current is large. - Applications - Block Diagram (1) Product without power-off function VIN (1) VOUT (2) Product with power-off function (1) VOUT (2) Short-circuit protection (2) Short-circuit protection ON/OFF Reference voltage Reference voltage (1) : Parasitic diode (2) : In case of a product with short-circuit...
