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

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

• Output voltage accuracy: ±2%

• On-chip saturation protector rising edge of input voltage

(at low input voltage)

• On-chip overcurrent limiter and thermal protection

• On-chip output transistor safe operation area protection
