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 www.DataSheet4U.com 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.
Features
Output current up to 1.5A No external components required Internal thermal overload protection Internal short-circuit current limiting Output transistor safe-area compensation Output voltage offered in 4% tolerance

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.
