TS78M00A Series

3-Terminal 500mA Positive Voltage Regulator

1/10

Version: A07

TO-220

TO-252

(DPAK)

General Description

The TS78M00A Series positive voltage regulators are identical to the popular TS7800A Series devices, except that

they are specified for only half the output current. Like the TS7800A devices, the TS78M00A Series 3-Terminal

regulators are intended for local, on-card voltage regulation.

Internal current limiting, thermal shutdown circuitry and safe-area compensation for the internal pass transistor

combine to make these devices remarkably rugged under most operating conditions. Maximum output current with

adequate heatsink is 500mA

This series is offered in 3-pin TO-220 & TO-252 package.

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.
