AP2112
600mA CMOS LDO REGULATOR WITH ENABLE
Description
The AP2112 is CMOS process low dropout linear regulator with
enable function, the regulator delivers a guaranteed 600mA (min.)
continuous load current.
The AP2112 is available with a fixed output voltage of 1.2V, 1.8V,
2.5V, 2.6V, or 3.3V. The LDO has an output accuracy of ±1.5% and a
very fast loop response providing excellent performance for dealing
with line and load transients. The AP2112 includes an auto discharge
function which connects the output to ground via 60 of resistance
when the device is disabled.
The regulator features low power consumption, and provides SOT25,
SOT89-5, and SO-8 packages. Previously SOT-23-5, SOT-89-5 and
SOIC-8 packages were respectively identified as SOT23-5, SOT89-5
and SO-8 but have been renamed to match the latest Diodes
Incorporated‘s nomenclature.

Application Note
In some unusual applications where a current load could be present at the output before the part is enabled the fold back current limiting may
prevent the part from starting. Applications with multiple supplies or negative supplies need to be evaluated for this possibility. Product testing
where a current source is applied before the part is enabled could be another area of concern. With a normal load as shown below there is no
interference of the fold back current limiting circuit.
