DESCRIPTION
The
μ
PC2918, 2925 and 2926 are three-terminal low dropout voltage regulators with the 1-A output. The
μ
PC2918
outputs 1.8 V, the
μ
PC2925 outputs 2.5 V and the
μ
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
O
= 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.
FEATURES
Output current capacity: 1 A
Low dropout voltage (V
DIF
= 0.5 V MAX. (at I
O
