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.
