Description

The AQ111 is a low dropout three terminal voltage regulator, offered in popular fixed options or an adjustable version that can set a precise voltage from 1.22V to 12V with two external resistors.

AQ111 is the only 1 Amp LDO regulator offered in the tiny PSOT-23 package. PSOT-23 is modified for lower thermal resistance and fits in the standard SOT-23 foot print. With a dropout voltage of less than one volt, the AQ111 can be used in applications where drop out voltage and size are an issue.

To assure accuracy within 1.5% over temperature the heart of the AQ111 is a selfcorrecting AcuRef™ bandgap reference.

On-chip current limit of AQ111 and thermal shutdown with hysteresis protects against any combination of overload and ambient temperature that might cause the junction temperature to exceed safe limits.
