IRU1502-33
MICROPOWER 1A LOW DROPOUT
PMOS VOLTAGE REGULATOR
FEATURES
Stable with Ceramic Capacitor
Small, Space Saving MLPM 6-Pin Package
Guaranteed < 1V Dropout at Full Load Current
Fast Transient Response
Ultra-Low Ground Current
Output Current Limiting
Built-In Thermal Shutdown
APPLICATIONS
High Efficiency Linear Regulator

DESCRIPTION
The IRU1502-33 is a PMOS low dropout, linear regulator
and it is capable of supplying 1A of continuous current
over line and temperature range. The IRU1502-33 is
stable with low value ceramic capacitors, ensures low
noise operation, improves load transient response and
enables a smaller circuit size.
IRU1502-33 features ultra low noise, fast start-up and
an excellent time and load response. This device also
includes built-in output protection with both current limit
and thermal shutdown.

Note 2: In general, Dropout voltage is defined as the
minimum differential voltage between VIN and VOUT re-
quired to maintain regulation at VOUT. In this specifica-
tion, it is the measured output voltage at specified con-
dition.
Note 3: Minimum load current is defined as the mini-
mum current required at the output in order for the out-
put voltage to maintain regulation.
Note 5: Guaranteed by design, but not tested in produc-
tion.
Note 6: All limits are guaranteed. All electrical charac-
teristics have temperature limits that are tested during
TA=258C at probing and tested at final production with
TA=1008C. All hot and cold limits are guaranteed by cor-
relating the electrical characteristics to process and tem-
perature variations.

PIN DESCRIPTION
No connection.
Ground pin.
The output of the regulator. A minimum of 4.7mF output capacitance must be connected
from this pin to ground to insure stability.
The power input pin of the regulator. A minimum of input capacitance must be connected
from this pin to ground to insure that the input voltage does not sag below the minimum
dropout voltage during the load transient response. This pin must always be higher than
the VOUT pin by the amount of dropout voltage (see electrical specification) in order for the
device to regulate properly.
