A voltage reference is an electronic device used to produce an accurate, stable voltage level for use in a variety of electronic circuits. It is usually required when precise accuracy, long-term stability, low power consumption, and isolating or separating from an electrical power source are important factors. It is an important device in power management integrated circuits (PMICs), as it is instrumental in maintaining precise voltage levels that are required for optimum processor performance, accurate system timing, and power saving schemes.

One such PMIC voltage reference is TLVH431AIDBZR, a precision micropower single supply shunt voltage reference.It is a 3-terminal adjustable device that can provide a stable reference voltage over a wide range of input and output voltages. It operates from a 2.7V to 10V supply voltage range, offers 400mV to 5.5V reference voltage range, consuming only 3.5μA of quiescent current. This device helps in reducing component count and cost of design, while guaranteeing a complete isolation from any unreliable power source supplying the power line.

This voltage reference uses two circuit elements to regulate the electrical current passing through it. First is a zener diode, which can act as a voltage-controlled resistor with a fixed characteristic voltage. The second is a transistor, which works as an amplifier to adjust the current flow to ensure a stable reference voltage. The zener diode maintains the reference voltage, while the transistor adjusts the current to provide a precise reference voltage. The reference voltage is then outputted at the device’s output pins.

The TLVH431AIDBZR can be used in a wide range of applications, including portable devices, computer systems, handsets, and automotive applications. In portable devices, it can be used to regulate the level of current passing through a battery, allowing for the optimum use of the available energy. In computer systems and handsets, it can be used to regulate the voltages delivered to various sensitive components, ensuring accurate and stable operation. In automotive applications, it can be used to regulate the voltage levels of the vehicle’s electrical system, ensuring the safe and efficient operation of the car.

The TLVH431AIDBZR voltage reference is an ideal device for a variety of low-power applications. It is extremely accurate, offering a wide range of output voltages and consuming only a small amount of power. It offers excellent isolation from sources of electrical noise and is highly robust, making it an excellent choice for precision voltage regulation in portable, computer, and automotive applications.
