Bipolar Power PNP Low Dropout Regulator Transistor

The MJE1123 is an applications specific device designed to provide low-dropou inear regulation for switching-regulator post regulators, battery powered systems and other applications. The MJE1123 is fully specf ed 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 IQ = 1.0 Amp, VCE= 7.0 Volts
• Excellent Saturation Voltage Characteristic, 0.2 Volts Maximum at 1.0 Amp
