500mA, Low-Voltage Linear Regulator in UMAX
General DescriptionThe 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.

Note 1:Dropout voltage is defined as VIN- VOUT, when VOUTis 100mV below the value of VOUTand when VIN= VOUT(NOM)+0.5V.
For 2.25V ≤VOUT≤4.0V, dropout voltage limits are linearly interpolated from the values listed. For VOUT< 4.0V, dropout
voltage limit is equal to the value for VOUT= 4.0V.
Note 2:Specifications to -40°C are guaranteed by design, not production tested.
