REF6033IDGKR

PMIC- Voltage Reference

REF6033IDGKR is a voltage reference regulator mainly used in battery charger systems and Voltage Regulators. It functions as an ideal voltage source, perfectly suited for complexries, that require multiple output-ranges and configurations. The REF6033IDGKR voltage referrence is specified as a low-dropout voltage referrence, with an output voltage accuracy of +/-12mV at room temperature.

Application Field

The REF6033IDGKR voltage reference is mainly used in applications requiring high accuracy and a high degree of temperature staibilty, such as battery charger systems, linear and switch mode voltage regulators, audio, and digital-to-analog converters. The reference is most commonly used for precision voltage references for shunt and series regulators, where it provides a stable reference for the circuits.

Working Principle

The REF6033IDGKR voltage reference uses an imprecise reference diode to stabilize the reference voltage. The diode is electrically isolated by a set of PNP transistors and a base leakage current is supplied to hold the diode in place. The resistor divider is configured so that the reference voltage is maintained at a fixed level. The REF6033IDGKR voltage reference is configured to run up to 30 mA, with a low output voltage of 0.36V. This voltage is further increased by adding external resistors, so that it can be adjusted to the voltage required for the application.

Conclusion

Overall, the REF6033IDGKR is a reliable voltage reference for applications requiring high accuracy and high temperature stability. It is simple and cost-effective to implement, and its low dropout voltage makes it an ideal choice for applications such as battery charger systems, linear and switch mode voltage regulators, audio, and digital-to-analog converters. This voltage reference provides the flexibility to manage different voltages and makes it suitable for a range of applications.
