BIPOLAR ANALOG INTEGRATED CIRCUIT
µ PC24A00 Series
THREE TERMINAL LOW DROPOUT VOLTAGE REGULATOR
The µPC24A00 Series is a low dropout voltage three terminal regulator that has realized a minimum voltage
differential between the I/O of no more than 1 V when the output current is 2 A through the employment of a PNP
transistor at the output stage.
Due to its ability to achieve a greater reduction in the power loss compared with conventional three-terminal
regulators, the µPC24A00 Series is ideal for use as the secondary side smoothing circuit of a power supply.
