TS78M00 Datasheet, PDF (1/8 Pages) Taiwan Semiconductor Company, Ltd – 3-Terminal Medium Current Positive Voltage Regulator

TS78M00 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 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
This series is offered in 3-pin TO-220, TO-252 package.

Absolute Maximum Rating
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.
