PJ7800B Series 3-Terminal Fixed
Voltage Positive Regulators
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.

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.

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, ...
