PJ7800 Series
3-Terminal Fixed Voltage Positive Regulators
These voltage regulators are monolithic integrated
circuits designed as fixed-voltage regulators for a
wide variety of applications including local, on-card
regulation. These regulators employ internal current
limiting, thermal shutdown, and safe-area
compensation.
FEATURES
Output Current up to 1 Ampere
No External Components Required
Internal Thermal Overload Protection
Internal Short-Circuit Current Limiting
Output Transistor Safe-Area Compensation
Output Voltage Offered in 4% Tolerance
CIRCUIT SCHEMATIC
With adequate heatsinking they can deliver output
currents up to 1 ampere.
Although designed primarily as a fixed voltage
regulator, these devices can be used with external
components to obtain adjustable voltages and currents.
PIN ARRANGEMENT
TO-220
TO-220F
Pin: 1.Input
2.Ground
3.Output
(Heatsink surface connected to Pin 2.)
Representative Schematic Diagram
Standard Application
TYPICAL CONNECTING CIRCUIT
A common ground is required between the input and
the output voltages. The input voltage must remain
typically 2.0V above the output voltage even during
the low point on the Input ripple voltage.
XX = these two digits of the type number indicate
voltage.
* = Cin is required if regulator is located an
appreciable distance from power supply filter.
** = Co is not needed for stability; however, it does
improve transient response.
