TS7800 Series 3-Terminal Fixed Positive Voltage Regulator TO-220 ITO-220 Pin Definition: 1. Input 2. Ground (tab) 3. Output 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. Features Standard Application Circuit Output Voltage Range 5 to 24V 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 A common ground is required between the input and the Ordering Information output voltages. The input voltage must remain typically 2.0V above the output voltage even during the low point on Part No. Package Packing the Input ripple voltage.
