General Description
The TS7800 series 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
ampere. Although designed primarily as a fixed voltage regulator, these devices can be used with external
components to obtain adjustable voltages and currents.
Features
Output Voltage Range 5 to 24V
Output current up to 1A
No external components required
Internal thermal overload protection
Internal short-circuit current limiting
Output transistor safe-area compensation
Output voltage offered in 4% 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.

Pulse testing techniques are used to maintain the junction temperature as close to the ambient temperature as
possible, and thermal effects must be taken into account separately.
This specification applies only for DC power dissipation permitted by absolute maximum ratings.
