MAX6145 - 3-Terminal Voltage References

General Description

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.

19-1177; Rev. 0; 12/96 SOT23, Low-Cost, Low-Dropout, 3-Terminal Voltage References _______________General Description 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).
