General Description
The MAX1806 low-dropout linear regulator operates
from a +2.25V to +5.5V supply and delivers a guaran-
teed 500mA load current with low 175mV dropout. The
high-accuracy (±1%) output voltage is preset at an
internally trimmed voltage (see
Selector Guide
) or can
be adjusted from +0.8V to +4.5V with an external resis-
tive-divider.
An internal PMOS pass transistor allows low 210μA
supply current, making this device ideal for portable
equipment such as personal digital assistants (PDAs),
cellular phones, cordless phones, and other equip-
ment, including base stations and docking stations.
Other features include an active-low, power-OK output
that indicates when the output is out of regulation, a
0.02μA shutdown mode, short-circuit protection, and
thermal shutdown protection. The MAX1806 comes in a
miniature 1.3W, 8-pin power-μMAX package with a
metal pad on the underside of the package.
