Datasheet Taiwan Semiconductor TS7809CI

TS7800 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 1A 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 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. Features Standard Application — 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 Ordering Information

TO-220 TS78xxCI ITO-220 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. …
