3-Terminal Low Current Positive Voltage Regulators

PJ78L00
3-Terminal Low Current Positive Voltage Regulators
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.

STANDARD APPLICATION
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.
