TOR Rectifier
DUAL 6A AND IA LOW DROPOUT
POSITIVE FIXED 1.5V AND 2.5V REGULATOR
FEATURES DESCRIPTION
El Guaranteed to Provide 1.5V and 2.5V Supplies The IRU1261, using a proprietary process, combines a
with 3.1V Input dual low dropout regulator with fixed outputs of 1 .5V and
El Fast Transient Response 2.5V in a single package with the 1.5V output having a
El 1% Voltage Reference Initial Accuracy minimum of 6A and the 2.5V having a IA output current
El Built-ln Thermal Shutdown capability. This product is specifically designed to pro-
vide well regulated supplies from 3.3V to generate 1.5V
APPLICATIONS for GTL+ termination resistor supply and 2.5V clock
a Pentium Hm Processor Applications supply for the new generation of the Pentium IITM pro-
cessor applications.

RMS Output Noise 1OHzNote 1: Low duty cycle pulse testing with Kelvin con-
nections is required in order to maintain accurate data.
Note 2: Dropout voltage is dehned as the minimum dif-
ferential voltage between VIN and Vow required to main-
tain regulation at Vow. It is measured when the output
voltage drops 1% below its nominal value.
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. Typically the resistor
dividers are selected such that it automatically main-
tains this current.
