TS7800A series
3-Terminal Fixed Positive Voltage Regulator
ITO-220
Pin assignment:
1. Input
2. Ground
3. Output
(Heatsink surface
connected to Pin 2)
Voltage Range 5V to 24V
Output Current up to 1.5A
General Description
These voltage regulators are monolithic integrated circuits designed as fixed-voltage regulators for a wide variety of
applications including local, on-card regulation. These regulators employ internal current limiting, thermal shutdown, and
safe-area compensation. With adequate heatsink they can deliver output currents up to 1.5 ampere.
Although designed primarily as a fixed voltage regulator, these devices can be used with external components to obtain
adjustable voltages and currents.
This series is offered in 3-pin TO-220, ITO-220 package.

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.
