MAX6125/MAX6141/
MAX6145/MAX6150/MAX6160
SOT23, Low-Cost, Low-Dropout,
3-Terminal Voltage References
General Description
Features
● 3-Pin SOT23 Package
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.
(MAX6125/MAX6141/MAX6145/MAX6150)
4-Pin SOT143 Package (MAX6160)
● Low, 200mV Dropout Voltage
● 75μA Supply Current, Independent of Input Voltage
● 15ppm/°C Typical Tempco (50ppm/°C, max)
● Stable for All Capacitive Loads up to 10nF
● Adjustable Output Voltage from 1.23V
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.
