TS7800I series
ITO-220
3-Terminal Fixed Positive Voltage Regulator
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 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 2% tolerance
Standard Application
Ordering Information
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
