General Description
The MAX1725/MAX1726 are ultra-low supply current,
low-dropout linear regulators intended for low-power
applications that demand the longest possible battery
life. Unlike inferior PNP-based designs, the MAX1725/
MAX1726s’ PMOS pass elements maintain an ultra-low
2μA supply current throughout their entire operating
range and in dropout. Despite their ultra-low power
consumption, the MAX1725/MAX1726 have tight output
accuracy (1.5%) and require just 1μF output capacitance
to achieve good load-transient response.
These regulators have a wide input voltage range
(+2.5V to +12V), making them excellent choices for
systems powered from two lithium-ion (Li+) cells and 9V
batteries. Other features include reverse-battery protec-
tion, short-circuit protection, and thermal protection.
The MAX1725 provides an adjustable 1.5V to 5V output
using an external resistor-divider. The MAX1726 pro-
vides factory preset 1.8V, 2.5V, 3.3V, or 5V output volt-
ages (see the
Ordering Information
). Both devices are
available in a tiny 5-pin SOT23 package.
