General Description
The MAX6125/MAX6141/MAX6145/MAX6150/MAX6160
low-dropout, micropower, three-terminal voltage refer-
ences 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
temperature 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.
