THREE-TERMINAL LOW DROPOUT VOLTAGE REGULATOR

DESCRIPTION

The µPC2918, 2925 and 2926 are three-terminal low dropout voltage regulators with the 1-A output. The µPC2918 outputs 1.8 V, the µPC2925 outputs 2.5 V and the µPC2926 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 IO= 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.
