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

„ Applications

• Low current consumption

• Power source for battery-powered devices

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)

• Power source for personal communication

devices

• Output voltage accuracy: ±2.0%

• Power source for home electric/electronic

• Output current:

50mA capable (3.0 V output product, VIN=5 V) Note1

75mA capable (5.0 V output product, VIN=7 V) Note1

appliances

• 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.
