LM4040D30IDCKR Description

Short technical summary and product information.

The LM4040D30IDCKR from Texas Instruments is a versatile and easy-to-use shunt voltage reference designed for a wide range of applications. This fixed-output device provides a stable 3V reference voltage and requires no external capacitors for stable operation, even with varying capacitive loads.

 

Key electrical characteristics include a low typical operating current of 45µA, with an operating range extending up to 15mA. The device offers tight output tolerances, with A Grade parts specified at a maximum of 0.1% and a temperature coefficient of 100ppm/°C. Lower grades (B, C, D) offer wider tolerances and temperature coefficients. It also features low output noise of 35µVRMS typical.

 

Packaged in a compact SOT-SC70 (DCK) 5-pin package, the LM4040D30IDCKR is suitable for space-constrained designs. It operates within a temperature range of -40°C to 85°C. The device is stable with all capacitive loads and does not require an output capacitor, simplifying circuit design.

 

This shunt voltage reference is ideal for applications requiring a precise and stable voltage reference where low power consumption is critical. Its robust design and small footprint make it a suitable choice for various electronic systems.
