SWITCHING REGULATOR

CONTROLLER(LOW VOLTAGE)



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.
