TS78M00 Series
Taiwan Semiconductor
3-Terminal 500mA Positive Voltage Regulator
FEATURES
The TS78M00 Series positive voltage regulators are
●
Output Voltage Range 5V & 12V
identical to the popular TS7800 Series devices, except
●
Output current up to 500mA
that they are specified for only half the output current.
●
No external components required
Like the TS7800 devices, the TS78M00 Series 3-
●
Internal thermal overload protection
Terminal regulators are intended for local, on-card
●
Internal short-circuit current limiting
voltage regulation. Internal current limiting, thermal

TYPICAL 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.
