8186 General Description
Designed specifically to meet the requirement for extended opera-tion of battery-powered equipment such as cordless and cellular telephones, the A8186SLU 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 3.3 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 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 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 inpu 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 A8186SLU is rated for operation over a temperature range of -20°C to+85°C.
