PJ7800B 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
Representative Schematic Diagram
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.

Standard Application
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.

* Pulse testing techniques are used to maintain the junction temperature as close to the ambient temperature as possible, and
thermal effects must be taken into account separately.
** This specification applies only for DC power dissipation permitted by absolute maximum ratings.
