Epson S1F70000 EPSON, LINEUP, S1F76300 Series

	S1F76300 Series
The S1F76300 series of CMOS switching regulators	featuring built-in RC oscillators, the S1F76330 series
comprises nine series—the S1F76310, S1F76380 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

2.0to 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.
