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 A8220SLH thru A8233SLH 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.

A82xxSLH

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 A8220SLH

thru A8233SLH 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., A82xxSLH , where “xx” is

the required output voltage in tenths.
