3-Terminal Fixed Positive Voltage Regulator

ITO-220

Pin assignment:

1. Input

Voltage Range 5V to 24V

Output Current up to 1A

2. Ground

3. Output

(Heatsink surface

connected to Pin 2)

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

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.
