MAX6125/MAX6141/ SOT23, Low-Cost, Low-Dropout, MAX6145/MAX6150/MAX6160 3-Terminal Voltage References General Description Features The MAX6125/MAX6141/MAX6145/MAX6150/MAX6160 3-Pin SOT23 Package low-dropout, micropower, three-terminal voltage references (MAX6125/MAX6141/MAX6145/MAX6150) offer 2.5V, 4.096V, 4.5V, 5.0V, and adjustable (1.23V to 4-Pin SOT143 Package (MAX6160) 12.4V) output voltages, respectively. Low, 200mV dropout Low, 200mV Dropout Voltage makes these devices ideal for 3V and 5V systems. Unlike 75A Supply Current, Independent of Input Voltage two-terminal references that waste battery current and require an external resistor, the MAX61xx familys supply 15ppm/C Typical Tempco (50ppm/C, max) current is virtually independent of input voltage variations, Stable for All Capacitive Loads up to 10nF which translates to longer battery life. Adjustable Output Voltage from 1.23V Initial accuracy for these devices is 1%. The output tem- to (V - 0.2V) (MAX6160) IN perature coefficient is typically 15ppm/C, and guaranteed Optimized for 3V/5V Operation to be less than 50ppm/C (except for the MAX6160). The MAX6125/MAX6141/MAX6145/MAX6150 are available in Applications 3-pin SOT23 and 8-pin SO packages. The MAX6160 is 3V/5V Systems available in 4-pin SOT143 and 8-pin SO packages.
