S1F76300
Series
The S1F76300 series of CMOS switching regulators
comprises nine series—the S1F76310, S1F76380 series featuring built-in RC oscillators, the S1F76330 series
requiring external crystal oscillators.
S1F76310, S1F76380 Series Built-in CR Oscillator Type
CMOS Switching Regulators
DESCRIPTION
The S1F76310, S1F76380 series of CMOS switching
regulators provide input voltage step-up and regulation
to a specified fixed voltage using an external coil. The
devices in these series incorporate precision, low-power
reference voltage generators and transistors for driving
an internal comparator. They feature low power con-
sumption, low operating voltages, voltage detection and
standby operation.
The devices offer a range of fixed output voltages, from
2.0 to 5.0V. The S1F76310 series features battery
backup and power-on clear, the S1F76380 series fea-
tures power-on clear and response compensation, the
S1F76380 series offer an output voltage temperature
characteristic for driving an LCD. They are available in
SOP3-8pin.
