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 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,

these devices deliver a regulated output at up to 200 mA (transient),

which is internally limited, providing short-circuit protection. Regu-

lated output voltages of 2.7, 2.8, 3.0, 3.2, 3.3, 3.6, 3.8, 4.0, and 5.0 V

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

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 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 A8405SLH

includes an ENABLE input to give the designer complete control over

power up, standby, or power down.

Dwg. PS-021-6

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.

*BYPASS (fixed regulators) or

ADJUST (A8405SLH-ADJ only).

* Output current rating is limited by input

voltage, duty cycle, and ambient temperature.

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., A8405SLH-xx , where “xx”

is the required output voltage in tenths or “ADJ” for adjustable.
