Description

Designed specifically to meet the requirement for extended operation of battery-powered equipment such as cordless and cellular telephones, the A8405SLH voltage regulators offer the reduced dropout voltage and quiescent current essential for maximum battery life. Applicable also to palmtop computers and personal data assistants, A8405SLH deliver a regulated output at up to 200 mA (transient), which is internally limited, providing short-circuit protection. Regulated output voltages of 2.7, 2.8, 3.0, 3.2, 3.3, 3.6, 3.8, 4.0, and 5.0 Vare currently provided. Other voltages, down to 2.0 volts, are available on special order.

A PMOS pass element provides a typical dropout voltage of only 100 mV at 100 mA of load current. The low dropout voltage permits deeper battery discharge before output regulation is lost. Quiescent current does not increase significantly 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. The A8405SLH includes an ENABLE input to give the designer complete control over power up, standby, or power down.

These devices are supplied in a thermally enhanced 5-lead smalloutline plastic package similar to the SOT-23, and fitting the SC-74A footprint. A8405SLH are rated for operation over a temperature rangeof -20 to +85.
