LM223 - THREE-TERMINAL 3A-5V POSITIVE VOLTAGE REGULATORS

General Description

The LM123, LM223, LM323 are three-terminal positive voltage regulators with a preset 5V output and a load driving capability of 3A.

New circuit design and processing techniques are used to provide the high output current without sacrificing the regulation characteristics of lower current devices.

LM123/LM223 LM323 THREE-TERMINAL 3A-5V POSITIVE VOLTAGE REGULATORS . . . . . OUTPUT CURRENT : 3A INTERNAL CURRENT AND THERMAL LIMITING TYPICAL OUPUT IMPEDANCE : 0.01Ω MINIMUM INPUT VOLTAGE : 7.5V POWER DISSIPATION : 30W TO-3 DESCRIPTION The LM123, LM223, LM323 are three-terminal positive voltage regulators with a preset 5V output and a load driving capability of 3A. New circuit design and processing techniques are used to provide the high output current without sacrificing the regulation characteristics of lower current devices. The 3A regulator is virtually blowout proof. Current limiting, power limiting and thermal shutdown provide the same high level of reliability obtained with these techniques in the LM209, 1A regulator.
