• Manufacturer Part Number: S1F78100Y2A
• Description: High Precision Voltage Regulators
• Manufacturer: Epson Electronics America, Inc.

S1F79100Y Series CMOS Negative Voltage Regulators
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
• Small difference between input and output voltage :
