Bipolar Power PNP
Low Dropout Regulator
Transistor
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
