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 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.

FEATURES

• Output current capacity: 1 A

• Low dropout voltage

VDIF = 0.5 V MAX. (IO = 0.5 A)

• Output voltage accuracy: VO ± 2%

• On-chip saturation protector rising edge of input voltage

(at low input voltage)

• On-chip over-current limiter and thermal protection

• On-chip output transistor safe operation area protection
