19-3192; Rev 1; 12/07 Low-Power, Fixed and Adjustable Referencewith Shutdown in SOT23MAX6037General DescriptionFeatures The MAX6037 family of low-dropout, micropower volt- ♦ Adjustable VOUT: 1.184V to 5V age references offer fixed and adjustable output volt- ♦ Fixed Outputs: 1.25V, 2.048V, 2.5V, 3.0V, 3.3V, age options ranging from 1.184V to 5V. Connect an external resistive-divider on the MAX6037_ADJ to and 4.096V adjust the output voltage from 1.184V to 5V. The other ♦ Shutdown Current < 500nA (max) devices in the MAX6037 family feature fixed output volt- ♦ 25ppm/°C (max) Temperature Coefficient (A Grade) ages of 1.25V, 2.048V, 2.5V, 3.0V, 3.3V, and 4.096V. The MAX6037 offers shutdown functionality with an ♦ ±0.2% (max) Initial Accuracy (A Grade) active-low shutdown (500nA, max). ♦ Low 100mV (max) Dropout Voltage at 1mA Load These series-mode voltage references operate from a Current 2.5V to 5.5V supply and consume 275µA (max) quies- ♦ 2.5V to 5.5V Input Voltage Range cent current. The output is stable driving loads from ♦ 5mA Sink and Source Current Capability 0.02µF to 1µF and can source and sink 5mA of load current. The MAX6037 offers a low temperature coeffi- ♦ Available in 5-Pin SOT23 Package cient of 25ppm/°C and initial accuracy of ±0.2% (max). ♦ Operates Over the Automotive Temperature The low dropout voltage (100mV, max at 1mA) and Range: -40°C to +125°C supply-independent, low supply current make the MAX6037 ideal for battery-powered applications. Typical Operating Circuit The MAX6037 is available in the miniature 5-pin SOT23 package and is specified over the -40°C to +125°C 2.5V TO 5.5V INPUT automotive temperature range.
