DESCRIPTION
S1F79100Y series voltage regulators provide step-
down and stabilization for an input voltage to a speci-
fied fixed voltage. The four devices in the series incor-
porate a precision, power-saving reference voltage gen-
erator, a transistorized differential amplifier and resis-
tors 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 (I
O
=10mA, V
O
=–5.0V)
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
