* Output current rating is limited by input voltage,
tion of battery-powered equipment such as cordless and cellular
telephones, the A8183SLU 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. An ENABLE input
gives the designer complete control over power up, standby, or power
down.
This device is supplied in a 6-lead small-outline plastic package
(similar to the SOT-89/TO-243AA) for surface-mount applications. The
A8183SLU is rated for operation over a temperature range of -20°C to
+85°C.
