PJ3800 Features
·Wide supply voltage operating range: 1.8 to 15 V
·Low current consumption: Typically 5.5 mA in operation, 1 mA or less in stand-by
·High speed operation is possible: Maximum 1 MHz
·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.
