PJ78L00
3-Terminal Low Current Positive Voltage Regulators
1-8
2002/07.rev.A
A common ground is required between the input and the
output voltages. The input voltage must remain typical
2.0V above the output voltage even during the low point
on the input ripple voltage.
*=Cin is required if regulator is located an appreciable
distance from from power supply filter.
**=Co is not needed for stability, however, it does
improve transient response.
he PJ78L00 Series of positive voltage Regulators are
inexpensive, easy-to-use devices suitable for a multitude
of applications that require a regulated supply of up to 100
mA. Like their higher powered PJ7800 Series cousins, these
regulators feature internal current limiting and thermal
shutdown making them remarkably rugged. No external
components are required with the PJ78L00 devices in many
applications.
These devices offer a substantial performance advantage
over the traditional zener diode-resistor combination, as
output impedance and quiescent current are substantially
reduced.

This specification applies only for DC power dissipation permitted by absolute maximum ratings.
Pulse testing techniques are used to maintain the junction temperature as close to the ambient temperature as possible. Thermal
effects must be taken into account separately. All characteristics are measured with a 0.33uF capacitor across the input and a
0.1uF capacitor across the output.
