PRELIMINARY INFORMATION

LOW-DROPOUT REGULATORS  
— HIGH EFFICIENCY  
Designed specifically to meet the requirement for extended opera-  
tion of battery-powered equipment such as cordless and cellular tele-  
phones, 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 at up to 100 mA  
(transient), which is limited only by package power dissipation. Regu-  
lated output voltages of 2.6, 2.7, 2.8, 2.9, 3.0 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  
125 mV at 50 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 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. 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 small-  
outline plastic package similar to the SOT-23, and fitting the SC-74A  
footprint. All devices are rated for operation over a temperature range  
of -20°C to +85°C.

Under any set of conditions, do not exceed a  
junction temperature of +150°C. See follow-  
ing pages.  
Always order by complete part number, e.g., A82xxSLM , where “xx” is  
the required output voltage in tenths.
