DESCRIPTION

The UTC L2800 which is incorporating a soft start function and short circuit detection function is a single-channel switching regulator control IC and is made for low voltage applications. Because the device has a low minimum operating voltage of 1.8V, so it is ideal for the power supply of battery-operated electronic equipment.

FEATURES

* Wide supply voltage operating range: 1.8V~15V

* Low current consumption: Typically 5.5mA in operation,1μA or less in stand-by

* High speed operation is possible: Maximum 1MHz

* The error amplifier gain is set inside the IC, so peripheral components are minimized.

* Incorporates a soft start circuit.

* Incorporates a timer-latch type short circuit detection circuit (SCP).

* Totem-pole type output with adjustable on/off current (for NPN transistors)

* Incorporates a stand-by function.
