MOS INTEGRATED CIRCUIT
µPD120Nxx Series
THREE-TERMINAL LOW-DROPOUT POSITIVE-VOLTAGE REGULATOR
(OUTPUT CURRENT: 0.3 A)
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.

Caution Use of conditions other than the above-listed recommended operating conditions is not a problem
as long as the absolute maximum ratings are not exceeded. However, since the use of such
conditions diminishes the margin of safety, careful evaluation is required before such conditions are
used. Moreover, using the MAX. value for all the recommended operating conditions is not
guaranteed to be safe.
