PRELIMINARY INFORMATION DATA SHEET

LOW-DROPOUT,

(Subject to change without notice)

3 V REGULATOR

November 14, 1994

LOW-DROPOUT, 3 V REGULATOR

— HIGH EFFICIENCY

Designed specifically to meet the requirement for extended opera-

tion 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,

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.

This device is supplied in an 8-lead small-outline plastic package

(SOIC) for surface-mount applications. The A8182SL is rated for

operation over a temperature range of -20°C to +85°C.

* Output current rating is limited by input voltage,

duty cycle, and ambient temperature. Under any

set of conditions, do not exceed a junction temp-

erature of +150°C. See next page.

† Fault conditions that produce excessive junction

temperature will activate device thermal shutdown

circuitry. These conditions can be tolerated but

should be avoided.
