LOW-DROPOUT, 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 A8182SL
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 3 V output at up to 150 mA.

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. Furthermore, qu...
