PD120Nxx Series
THREE-TERMINAL LOW-DROPOUT POSITIVE-VOLTAGE REGULATOR
(OUTPUT CURRENT: 0.3 A)
MOS INTEGRATED CIRCUIT
DESCRIPTION
The
µ
PD120Nxx 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
µ
PD120Nxx series, this contributes to the miniaturization of the application set.

Caution Product quality may suffer if the absolute maximum rating is exceeded even momentarily for any
parameter. That is, the absolute maximum ratings are rated values at which the product is on the
verge of suffering physical damage, and therefore the product must be used under conditions that
ensure that the absolute maximum ratings are not exceeded.

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.
