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.

Output Voltage Range 5 to 24V
Output current up to 500mA
No external components required
Internal thermal overload protection
Internal short-circuit current limiting
Output transistor safe-area compensation
Output voltage offered in 2% tolerance
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.
