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 A8184SLT 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 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
90 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 ap-
proached, 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.
This device is supplied in a small-outline plastic transistor package
(SOT-89/TO-243AA) for surface-mount applications. The A8184SLT is
rated for operation over a temperature range of -20°C to +85°C. A
similar device with an ENABLE input for control over sequential power
up, standby, or power down is the A8183SLU.

any set of conditions, do not exceed a junction
temperature of +150°C. See next page.
I Palmtop Computers
† Fault conditions that produce excessive junction
temperature will activate device thermal
shutdown circuitry. These conditions can be
tolerated but should be avoided.
