TS78M00 Series

3-Terminal 500mA Positive Voltage Regulator

1/5

Version: D14

TO-252

(DPAK)

General Description

The TS78M00 Series positive voltage regulators are identical to the popular TS7800 Series devices, except that

they are specified for only half the output current. Like the TS7800 devices, the TS78M00 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

Standard Application 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.
