General Description
The TS78M05A Series positive voltage regulators are identical to the popular TS7805 Series devices, except that
they are specified for only half the output current. Like the TS7805 devices, the TS78M05A 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
Features
● Output Voltage 5V
● Output current up to 500mA
● Internal thermal overload protection
● Internal short-circuit current limiting
● Output transistor safe-area compensation
● Output voltage offered in 2% tolerance
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.
