TS7800
3-Terminal Fixed Positive Voltage Regulators
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 heatsinking 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.

Notes:
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 part number indicate output 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.
