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.

Ordering Information
Part No.
TS78xxCZ C0
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
.
