Acutechnology Semiconductor AQ533
The AQ533 is an ultra-low dropout voltage regulator capable of delivering 500 mA to the load. It is adjustable and can set a precise voltage from 1.22V to 12V with two external resistors. The AQ533 meets all specifications down to 1.22V output, unlike CMOS LDO’s which loose performance with outputs below 2.25V.| Part No. | AQ533 |

GENERAL DESCRIPTION
The enable pin provides a remote turn-off for low power consumption. It draws virtually zero current in shutdown mode and implements Sequential, Ratiometric, or Simultaneous sequencing schemes. This also allows for a separate bias connection from the pass transistor in order to achieve ultra low dropout from VIN to VOUT. Reverse current protection blocks current flowing from VOUT to VIN when the AQ533 is disabled. No current flows. To assure accuracy within 1.5% over temperature, the heart of the AQ533 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.APPLICATIONS
