MAX6150:SOT23, Low-Cost, Low-Dropout, 3-Terminal Voltage References

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. 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.
