HIGH OPERATING VOLTAGE CMOS VOLTAGE REGULATOR
S-812C Series
Seiko Instruments Inc.
1
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 shutdown 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
A, Max. 1.8 A (3.0 V)
Output voltage:
2.0 to 6.0 V, selectable in 0.1 V steps
Output voltage accuracy: 2.0%
Output current:
50 mA capable (3.0 V output product, V
IN
=5 V)
*1
75 mA capable (5.0 V output product, V
IN
=7 V)
*1
Dropout voltage:
Typ. 120 mV (V
OUT
= 5.0 V, I
OUT
= 10 mA)
Power-off function:
Polarity for shutdown switch or removal of the shutdown 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
Operating voltage:
16 V maximum.
*1. Attention should be paid to the power dissipation of the package when the output current is large.
Applications
Power source for home electric/electronic appliances
Power source for battery-powered devices
Power source for personal communication devices
