The MJE1123 is an applications specific device designed to provide low–dropout linear regulation for switching–
regulator post
regulators, battery powered systems and other applications. The MJE1123 is fully specified in the saturation region and exhibits the following main features: High Gain Limits Base–Drive Losses to only 1–2% of Circuit Output Current Gain is 100 Minimum at IC = 1.0 Amp, VCE = 7.0 Volts Excellent Saturation Voltage Characteristic, 0.2 Volts Maximum at 1.0 Amp MAXIMUM RATINGS (TC = 25°C Unless Otherwise Noted.)
