AQ533 Ultra-Low Dropout 500mA Voltage Regulator Product Specification Revision 1.7 September 13, 2006 General Description 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. 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.
