Pb Free Plating Product
1.2V/1.32V 0.4A Low Dropout Fixed-Mode Regulator
„ Features
„ General Description
- 1.2V maximum dropout at full load current
- Fast transient response
- Output current limiting
- Built-in thermal shutdown
- Needs Only 1uF Capacitor for stability
- Good noise rejection
- 3-Terminal Fixed 1.2V/1.32V
- Low ESR Ceramic Capacitor for output stability
- Packages:SOT23
- RoHS Compliant
APE891X is a low dropout fixed-mode regulator
with minimum of 0.4A 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 1.2V
dropout at full load current making it ideal to provide
well-regulated outputs of 1.2V/1.32V with 2.4V to 6V input
supply.

FUNCTION
The input pin of regulator. A minimum of 1uF is 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 1.2V higher than Vout in order
for the device to regulate properly.

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. Load regulation is measured at the output lead = 1/18” from the package.
Note2: Line and load regulation are guaranteed up to the maximum power dissipation of 5W. 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. At 6V input/output differential the
device is guaranteed to regulate if the output current is greater than 10mA.
