Low Dropout 1 Amp Voltage Regulator
Product Specification Revision 1.5 September 19, 2005
General Description
The AQ1117 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. AQ1117 is offered in SOT-89 which has a lower thermal resistance and fits in smaller foot print than a standard SOT-223. With a dropout voltage of less than one volt, the AQ1117 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 AQ1117 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.
