ISL21009DFB812Z

Power Management Integrated Circuits (PMICs) play a major role in today’s sophisticated electronic devices. They are used to regulate and control power in consumer and industrial applications. Voltage references are one type of PMICs which are widely used in the industry to provide precise and stable voltage reference sources. A voltage reference is an electronic circuit that provides a precise output voltage that is proportional to a precise current or voltage supply. The ISL21009DFB812Z voltage reference is a monolithic highly-precision, low-dropout voltage reference designed for use in low- and medium-power, low-voltage applications.

The ISL21009DFB812Z is available in a tiny 5-bump WLP (1.4mm x 1.4mm) package and operates in the temperature range of -40°C to +105°C. It can operate from a single input voltage of 2.2V to 10V and provides a precise output voltage of 0.8V with a very low dropout voltage of 0.15V at 100mA. It achieves an outstanding accuracy of ±0.1% under specified load, line, and temperature conditions. This makes it a reliable and robust power source for applications in embedded systems, industrial and automotive system control, battery charging, medical equipment, portable analytical systems, and voltage monitoring.

The ISL21009DFB812Z voltage reference operates on a simple principle. It consists of two transistors in series with a feedback loop consisting of resistors and capacitors. The voltage generated across the series transistors is equal to the sum of the base-to-emitter voltages of each transistor. The feedback loop is used to regulate the output voltage and maintain a constant voltage across the transistors. The voltage reference is then connected to the power supply of the system and the output voltage is regulated.

The ISL21009DFB812Z flame-retardant WLP-5 package is designed for excellent power density and improved thermal capability. It has an input voltage range of 2.2V to 10V and a nominal output voltage of 0.8V. It enables designers to reduce size and simplify PC board routing. The ISL21009DFB812Z also offers a low dropout voltage of 150mV and a low quiescent current of 1.2mA. The excellent performance of this voltage reference provides designers with the reliability and accuracy they need in their applications.

In conclusion, the ISL21009DFB812Z voltage reference offers excellent accuracy and power density. It is well suited for a wide range of industrial, automotive and consumer applications. Its low-dropout voltage and low quiescent current make it a reliable power source for applications in embedded systems, industrial and automotive system control, battery charging, medical equipment, portable analytical systems, and voltage monitoring.
