TS78M00 Series

3-Terminal 500mA Positive Voltage Regulator

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.
