LM4051CIM3-1.2+T

Voltage Reference Overview

The LM4051CIM3-1.2+T is a precision micropower shunt voltage reference manufactured by Analog Devices Inc./Maxim Integrated, housed in an ultra-small SOT-23 surface-mount package (3mm x 1.3mm). This device provides a fixed reverse breakdown voltage of 1.225V and operates within a wide current range of 60µA to 12mA. It features an initial accuracy of 0.5% at 25°C and maintains a maximum temperature coefficient of 50ppm/°C across the industrial temperature range of -40°C to +85°C. The component exhibits low output noise of 20µVrms from 10Hz to 10kHz and requires no external stabilizing capacitor, ensuring stability with any capacitive load.

Voltage Reference Procurement Notes

Verify that the ordering suffix '+T' corresponds to tape-and-reel packaging as specified by the manufacturer's documentation. Confirm the 'C' grade designation aligns with the required 0.5% initial accuracy specification. Ensure the operating environment remains within the -40°C to +85°C industrial temperature range defined for this specific part variant. Cross-reference the datasheet to confirm compatibility with system power budgets given the 60µA minimum operating current requirement.

Voltage Reference Selection Notes

Select this component when space constraints necessitate the use of the subminiature SOT-23 package over larger alternatives like SC70. Choose this fixed-voltage version specifically when a stable 1.225V reference is required rather than an adjustable output. Consider this device for designs requiring low dynamic impedance and minimal output noise in the 10Hz to 10kHz bandwidth. It is suitable for applications demanding high precision without the complexity of external compensation components.

Voltage Reference Part Context

The LM4051 series comprises precision two-terminal shunt-mode bandgap voltage references available in multiple fixed reverse breakdown voltages including 1.225V, 2.048V, 2.500V, 3.000V, 3.3V, 4.096V, and 5.000V. These devices are designed for space-critical applications and offer grades ranging from 0.1% to 0.5% initial accuracy. The series shares common characteristics such as a 50ppm/°C temperature coefficient and wide operating current capability, making it a versatile family for various reference needs.
