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
A common ground is required between the input and the output voltages. The input voltage must remain typically 2.0V
