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.

Note: The suggested land pattern dimensions have been provided for reference only, as actual pad layouts may vary depending on application. These

dimensions may be modified based on user equipment capability or fabrication criteria. A more robust pattern may be desired for wave soldering

and is calculated by adding 0.2 mm to the ‗Z‘ dimension. For further information, please reference document IPC-7351A, Naming Convention for

Standard SMT Land Patterns, and for International grid details, please see document IEC, Publication 97.

Note: For high voltage applications, the appropriate industry sector guidelines should be considered with regards to creepage and clearance distances

between device Terminals and PCB tracking.
