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.
