µPD120Nxx Series
THREE-TERMINAL LOW-DROPOUT POSITIVE-VOLTAGE
REGULATOR (OUTPUT CURRENT: 0.3 A)
MOS INTEGRATED CIRCUIT
DESCRIPTION
The µPD120Nxx series provides low-voltage output
regulators with the output current capacitance of 0.3 A. The output voltage varies according to the product (1.5 V, 1.8 V, 2.5 V, or 3.3 V). The circuit current is low due to the CMOS structure, so the power consumption in the ICs can be reduced. Moreover, since ICs are mounted in the small package of the µPD120Nxx series, this contributes to the miniaturization of the application set.
FEATURES
Output current: 0.3 A On-chip overcurrent protection circuit On-chip thermal protection circuit Small circuit operation current: 60 µA TYP.
APPLICATIONS
Digital TV, Audio, HDD, DVD, etc.
