PACKAGE ORDERING INFORMATION

1.2V/1.32V 1A LOW DROPOUT FIXED-MODE REGULATOR

APE891X is a low dropout fixed-mode regulator with

minimum of 1A output current capability. The product is

specifically designed to provide well-regulated supply for low

voltage IC applications such as high-speed bus termination

and low current 1.2V/1.32V logic supply.

APE891X is guaranteed to have lower than 1.5V

dropout at full load current making it ideal to provide well-

regulated outputs of 1.2/1.32 with 3V to 6V input supply.

Note1. See thermal regulation specifications for changes in output voltage due to heating effects. Line and load

regulation are measured at a constant junction temperature by low duty cycle pulse testing.

Note2. Line and load regulation are guaranteed up to the maximum power dissipation of 15W. Power dissipation is

determined by the difference between input and output differential and the output current. Guaranteed maximum

power dissipation will not be available over the full input/output range.

Note3. Quiescent current is defined as the minimum output current required in maintaining regulation.

PIN DESCRIPITON

The input pin of the regulator. A minimum of 1uF 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 1.5V higher than VOUT in

order for the device to regulate properly.

Ground
