LM4040B10IDBZT is a low-dropout precision voltage reference (PMIC - Voltage Reference). It is designed to provide a precision 10V reference voltage output, ideal for applications requiring low noise, high accuracy and fast circuit response. As compared to conventional reference sources, the LM4040B10IDBZT provides stable voltage references over time and temperature due to its proprietary design.

The LM4040B10IDBZT offers input lines for setting resistor ratios. The integrated precision regulator topology uses an internal voltage reference circuit working in negative temperature coefficient (NTC) mode. It is based on a zener diode released with a series resistor and a bandgap reference to adjust the output current and thermal drift. All of this ensures a stable output voltage over the entire operating range.

The LM4040B10IDBZT provides up to a 0.5% tolerance over temperature. The voltage reference can be adjusted to an output voltage from 8.0 V to 13.5 V VREF. It can also withstand up to 60 mA of load current and can typically sustain a power dissipation rating to 40 ?W.

The LM4040B10IDBZT is housed in a small, space saving SOT-23 package. It is available in an extended temperature range from –55°C to 150°C and has reverse polarity protection. The device can be incorporated in any topology that requires a high accuracy 10V reference voltage.

In conclusion, the LM4040B10IDBZT is ideal for applications requiring a precision low-dropout voltage reference, such as automotive, energy management, industrial and medical systems. Its wide temperature range and small package size makes it an ideal choice for space-constrained applications. The device offers high accuracy and fast circuit response, ensuring reliable operation, even under extreme temperature and voltage conditions.
