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.
♦ 3-Pin SOT23 Package (MAX6125/41/45/50)
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 to (V - 0.2V) (MAX6160)
IN
Initial accuracy for these devices is ±1%. The output
te mp e ra ture c oe ffic ie nt is typ ic a lly 15p p m/°C, a nd
g ua ra nte e d to b e le s s tha n 50p p m/°C (e xc e p t
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.
♦ Optimized for 3V/5V Operation
