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.
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.
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

Note 1: Output or reference voltage temperature coefficients defined as the worst case voltage change divided by the tatal
temperature range.
Note 2: Regulations is measured at constant junction temperature, using pulse testing with a low duty cycle. Changes in output
voltage due to heating effects are covered under the specification for thermal regulation.
Note 3: Line regulation is tested at 125℃ for I
L

Note 4: Dropout voltage is defined as the input to output differential at which the output voltage drops2% below its nominal value
measured at 1V differential.
Note 5: Ground pin current is the regulator quiescent current. The total current drawn from the source is the sum of the ground pin
current and output load current.
Note 6: Thermal regulation is the change in output voltage at a time T after a change in power dissipation, excluding load or line
regulation effects. Specifications are for a 200mA load pulse(3W pulse) for T = 10ms.
