1 / 26 page Rev.1.0 Seiko Instruments Inc. 1 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 low- power portable devices. Combination of power-off function and short-current protection can be selected. Features • Low current consumption Operating current: Typ. 1.0 µA, Max. 1.8 µA (3.0 V) • Output voltage: 2.0 to 6.0 V (0.1 V step) • Output voltage accuracy: ±2.0% • Output current: 50mA capable (3.0 V output product, VIN=5 V) Note1 75mA capable (5.0 V output product, VIN=7 V) Note1 • Dropout voltage Typ. 120 mV (VOUT = 5.0 V, IOUT = 10 mA) • 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 mA 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.
