General Description
The MAX6125/MAX6141/MAX6145/MAX6150/MAX6160
low-dropout, micropower, three-terminal voltage references
offer 2.5V, 4.096V, 4.5V, 5.0V, and adjustable (1.23V to
12.4V) output voltages, respectively. Low, 200mV dropout
makes these devices ideal for 3V and 5V systems. Unlike
two-terminal references that waste battery current and
require an external resistor, the MAX61xx family’s supply
current is virtually independent of input voltage variations,
which translates to longer battery life.
Initial accuracy for these devices is ±1%. The output tem-
perature coefficient is typically 15ppm/°C, and guaranteed
to be less than 50ppm/°C (except for the MAX6160). The
MAX6125/MAX6141/MAX6145/MAX6150 are available in
3-pin SOT23 and 8-pin SO packages. The MAX6160 is
available in 4-pin SOT143 and 8-pin SO packages.
