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.
FEATURES
• Output current capacity: 1 A
• Low dropout voltage (VDIF = 0.5 V MAX. (at IO = 0.5 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
