Features, Applications

Designed specifically to meet the requirement for extended operation of battery-powered equipment such as cordless and cellular telephones, the A8226SLM thru A8233SLM voltage regulators offer the reduced dropout voltage and quiescent current essential for maximum battery life. Applicable also to palmtop computers and personal data assistants, these devices deliver a regulated output 100 mA (transient), which is limited only by package power dissipation. Regulated output voltages of and 3.3 are 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 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 A8226SLM thru A8233SLM include ENABLE inputs 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. All devices are rated for operation over a temperature range to +85C.

* Absolute maximum peak output current rating is 100 mA; absolute maximum input voltage IO = (TJ TA)/([VI VO] RJA x dc) (150 TA)/([VI VO] x 1.00) Output current rating can be increased (to 100 mA maximum) by additional heat sinking or reducing the duty cycle.
