PMIC - Voltage Reference

PMIC voltage references are semiconductor devices that produce a predetermined reference voltage when provided with a supply voltage (VCC). The LT6657BHMS8-2.5#TRPBF is an ideal voltage reference device for applications such as shunt or series regulators, instrumentation amplifier circuits, and power converters.The LT6657BHMS8-2.5#TRPBF is a precision 2.5V low-noise voltage reference with low output drift of ±2ppm/°C. It typically features a temperature coefficient of 0.2ppm/°C, low input voltage (2.7V to 5.25V), low offset voltage of 0.05mV, high accuracy of ±0.06%, and low output noise of 0.88μVrms. The voltage reference features a fast transient response time of 3.6µs, low power consumption of 10µA max, and a wide operating temperature range of -40°C to 125°C. It includes an active burn-in that compensates for device temperature characteristics and reduces output drift.The LT6657BHMS8-2.5#TRPBF provides accurate and stable references for precision-level control of low-voltage circuits. It is used in shunt regulators to provide highly accurate output voltage references, in buck and boost regulator circuits, in high-side current sensing applications, in DC-DC converters, and in many other high-precision applications. Its low-noise, low-drift, and high accuracy enables the device to maintain high performance in applications that require very precise output voltages or current levels.The LT6657BHMS8-2.5#TRPBF is also a robust and reliable voltage reference device. It includes a wide range of protection mechanisms to protect the device from fault conditions such as overtemperature, overvoltage, and ESD. The device is further protected with a built-in overvoltage protection circuit which shuts down the device if the input voltage exceeds the rated operating voltage.The LT6657BHMS8-2.5#TRPBF working principle is based on a band gap voltage reference. In a band gap or Zener voltage reference, the device uses a combination of two resistor-capacitor (RC) circuits in a negative feedback arrangement to compare their respective voltages and generate a reference voltage. The reference voltage is determined by the ratio of the two resistors and is kept constant over temperature and output current variations.The LT6657BHMS8-2.5#TRPBF produces a very stable and accurate reference voltage, making it well suited for use in low-voltage power control and precision reference circuits. It has been widely adopted in a variety of applications, including shunt and series regulators, instrumentation amplifiers, and power converters. Thanks to its low-noise, low-drift, and high accuracy, it is a preferred choice for high-precision and system level applications.
