Three-Amperes Positive Voltage Regulators

This family of fixed voltage regulators are monolithic integrated circuits capable of driving loads in excess of 3.0 A. These three–terminal regulators employ internal current limiting, thermal shutdown, and safe–area compensation. Devices are available with improved specifications, including a 2 output voltage tolerance, on AC–suffix 5.0, 12 and 15 V device types.

Although designed primarily as a fixed voltage regulator, these devices can be used with external components to obtain adjustable voltages and currents. This series of devices can be used with a series–pass transistor to supply up to 15 A at the nominal output voltage.
