L2800 Features

*Wide supply voltage operating range: 1.8V~15V
*Low current consumption: Typically 5.5mA in  operation,1|ìA 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.
