omLow Voltage Switching Regulator Controller
t4U.che PJ3800 is a single-channel switching regulator
T econtrol IC for low voltage applications incorporating a
hesoft start function and short circuit detection function.
taSThe device has a low minimum operating voltage of 1.8 V and
ais ideal for the power supply of battery-operated electronic
.Dequipment.

SOP-8
TSSOP-8
Pin 1. Error amplifier inverting input
2. Soft Star & SCP
3. Power supply
z Wide supply voltage operating range: 1.8 to 15 V
mz Low current consumption: Typically 5.5 mA in
operation, 1 mA or less in stand-by
oz High speed operation is possible: Maximum 1 MHz
.cz The error amplifier gain is set inside the IC, so
peripheral components are minimized.
Uz Incorporates a soft start circuit.
t4z Incorporates a timer-latch type short circuit detection
ecircuit (SCP).
ez Totem-pole type output with adjustable on/off current
h(for NPN transistors)
z Incorporates a stand-by function.
