1 / 11 page LM123QML www.ti.com SNVS393A – DECEMBER 2010 – REVISED APRIL 2013 LM123QML 3-Amp, 5-Volt Positive Regulator Check for Samples: LM123QML 1 FEATURES DESCRIPTION The LM123 is a three-terminal positive regulator with 2 • 3 Amp Output Current a preset 5V output and a load driving capability of 3 • Internal Current and Thermal Limiting amps. New circuit design and processing techniques • 0.01 Ω Typical Output Impedance are used to provide the high output current without sacrificing the regulation characteristics of lower • 7.5V Minimum Input Voltage current devices. • 30W Power Dissipation The 3 amp 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 LM109 1 amp regulator. No external components are required for operation of the LM123. If the device is more than 4 inches from the filter capacitor, however, a 1 μF solid tantalum capacitor should be used on the input. A 0.1 μF or larger capacitor may be used on the output to reduce load transient spikes created by fast switching digital logic, or to swamp out stray load capacitance. An overall worst case specification for the combined effects of input voltage, load currents, ambient temperature, and power dissipation ensure that the LM123 will perform satisfactorily as a system element. For applications requiring other voltages, see LM150 series adjustable regulator data sheet. Connection Diagram Figure 1.
