General Description

The AP2318A is a series of ultra low dropout

regulators optimized for low voltage applications

where transient response and minimum input voltage

are critical.

The AP2318A provides current limit and thermal

shutdown function. Its circuit includes a trimmed

bandgap reference to assure output voltage accuracy to

be within ±1.5%. On-chip thermal shutdown provides

protection against any combination of overload and

ambient temperatures that would cause excessive

junction temperatures.

The AP2318A has adjustable version, which can set

the output voltage through two external resistors.

The AP2318A is available in the standard DFN-3x3-8

and PSOP-8 packages.
