Low Dropout 1 Amp Voltage Regulator
Product Specification Revision 1.5 September 13, 2006
General 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 and thermal shutdown with hysteresis protects against any combination of overload and ambient temperature that might cause the junction temperature to exceed safe limits.
