LINEAR INTEGRATED CIRCUIT
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.
