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.
