TS78M00A series
3-Terminal Medium Current Positive Voltage Regulator
Pin assignment:
1. Input
2. Ground
3.
Output
(Heatsink surface
connected to Pin 2)
Voltage Range 5V to 24V
Output Current up to 0.5A
General Description
The TS78M00A 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 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.
Features
Output current up to 0.5A
No external components required
Internal thermal overload protection
Internal short-circuit current limiting
Output transistor safe-area compensation
Output voltage offered in 2% tolerance

Note: Where xx denotes voltage option.
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.
