PC2918,2925,2926

THREE-TERMINAL LOW DROPOUT VOLTAGE REGULATOR

DESCRIPTION

The

PC2918, 2925 and 2926 are three-terminal low dropout voltage regulators with the 1-A output. The

PC2918

outputs 1.8 V, the

PC2925 outputs 2.5 V and the

PC2926 outputs 2.6 V. Since these regulators use a PNP

transistor for the output stage, they achieve a low dropout voltage of 0.7 V TYP. at I

= 1 A and minimize the power

dissipation of the IC. As a result, these regulators can be used to realize sets with lower voltage and power

dissipation.
