_______________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.

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.
