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

Ordering Information
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.

Note: Where xx denote voltage option
* = 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.
