Description

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
A8184SLT 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 A8184SLT 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.

A8184SLT 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.
