MOS INTEGRATED CIRCUIT
PD120Nxx Series
THREE-TERMINAL LOW-DROPOUT POSITIVE-VOLTAGE REGULATOR
(OUTPUT CURRENT: 0.3 A)

DESCRIPTION
The
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
PD120Nxx 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
A TYP.
APPLICATIONS
Digital TV, Audio, HDD, DVD, etc.

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.

: 0.1
F or higher. Set this value according to the length of the line between the regulator and INPUT pin. Be sure
to connect C

to prevent parasitic oscillation. If using a laminated ceramic capacitor, it is necessary to ensure
that C

is 0.1
F or higher for the voltage and temperature range to be used.
C
OUT

to prevent oscillation and improve excessive load regulation. Place
C

: If the OUTPUT pin has a higher voltage than the INPUT pin, connect a diode.
D

: If the OUTPUT pin has a lower voltage than the GND pin, connect a schottky barrier diode.
Caution Make sure that no voltage is applied to the OUTPUT pin from external.

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.
