S1F79100Y Series

S1F79100Y Series CMOS Negative Voltage Regulators

DESCRIPTION

S1F79100Y series voltage regulators provide step- down and stabilization for an input voltage to a specified fixed voltage. The four devices in the series incorporate a precision, power-saving reference voltage gen- erator, a transistorized differential amplifier and resistors for determining the output voltage.

The S1F79100Y series is available in 3-pin plastic SOT89s.

FEATURES

Ample lineup : 5 kinds are available in the range from –1.5V to –5V.

Small difference between input and output voltage : Typ. 0.17V (IO=10mA, VO=–5.0V)

Built-in highly stable reference voltage source : Typ. –1.0V

Small output voltage temperature coefficient : Typ. – 100ppm/˚C

Wide operating voltage range : 15V Max.

APPLICATIONS

Fixed-voltage power supplies for battery-operated equipment such as portable video cassette recorders, video cameras and radios

Fixed-voltage power supplies for communications equipment

High-stability reference voltage generators
