8186 LOW-DROPOUT, 3.3 V REGULATOR 8186 LOW-DROPOUT, 3.3 V REGULATOR — HIGH EFFICIENCY Designed specifically to meet the requirement for extended operation of battery-powered equipment such as cordless and cellular telephones, the A8186SLU voltage regulator offers the reduced dropout voltage and quiescent current essential for maximum battery life. Applicable also to palmtop computers and personal data assistants, the device delivers a regulated, continuous 3.3 V output at up to 75 mA under normal operating conditions, or to 150 mA (transient) under worst-case conditions. A PMOS pass element provides a typical dropout voltage of only 85 mV at 60 mA of load current. The low dropout voltage permits deeper battery discharge before output regulation is lost.
