SCI7810Y Series
SCI7810Y Series
Positive output voltage regulator
Lower operating current
Higher output voltage regulation capability
OUTLINE
SCI7810Y series a fixed type voltage regulator developed utilizing CMOS silicon gate process. It is configured
with a reference circuit, differential amplifier, output control transistor and voltage setting resistor of high accuracy
and low operating current.
Output voltage is fixed in IC. This series supports a variety of output voltages.
FEATURES
Low operating current
Smaller temperature difference between
output and input voltages
Smaller output voltage temperature coefficient
Larger operating voltage range
Higher output voltage regulation capability
