Overview

8182 PRELIMINARY INFORMATION DATA SHEET LOW-DROPOUT, (Subject to change without notice) 3 V REGULATOR November 14, 1994 8182 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.

PS-020 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, quiescent current does not increase as the dropout voltage is approached, an ideal feature in standby/resume power systems where data integrity is crucial.
Regulator accuracy and excellent temperature characteristics are provided by a bandgap reference.
An ENABLE input and RESET output gives the designer complete control over power up, standby, or power down.
