PJ4800 Series
400mA Low Dropout Voltage Regulators
T he series of fixed-voltage monolithic micropower voltage
regulators is designed for a wide range of applications.
Thes device excellent choice fo use in battery-power
application. Furthermore, the quiescent current increases on
slightly at dropout, which prolongs battery life.
This series of fixed-voltage regulators features very low
quiescent current ( 100mA Typ.) and very low drop output

voltage (Typ. 60mV al light load and 600mV at 400mA).
This includes a tight initial tolerance of 0.5% typ., extremely
good load and line regulation of 0.05% typ., and very low
output temperature coefficient.
This series is offered in 3-pin TO-263, TO-220, TO-252 &
SOT-223 package, and in 5-pin TO-220 & TO-263 package
with shutdown input.
