2905A

•Output current in excess of 1.0 A
•Low dropout voltage VDIF = 0.7 V TYP. (at I_O = 1 A)
•On-chip overcurrent and thermal protection circuit
•On-chip output transistor safe area protection circuit

The PC2933A, 2905A of low dropout voltage three terminal positive regulators is constructed with PNP output transistor. The PC2933A, 2905A feature the ability to source 1 A of output current with a low dropout voltage of typically 0.7 V.

The power dissipation of the PC2933A, 2905A can be drastically reduced compared with the conventional three terminal positive voltage regulators that is constructed with NPN output transistor. Also, this series corresponds to the low voltage output (3 V, 3.3 V) which is not in the conventional low dropout regulators ( PC2400A series).
