LT1021CCN8-5#PBF applications and working principles can be summarized under PMIC (Power Management Integrated Circuit) Voltage Reference. Voltage reference is an important component in power management that provides highly stable voltage reference sources for other components of the system. The LT1021CCN8-5#PBF is a precision voltage reference, meaning it provides a stable voltage output over varying input and temperature ranges.The LT1021CCN8-5#PBF is a three pin through-hole mounted IC with a small footprint and allows for easy mounting on printed circuit boards. Its body size is just 3mm x 3mm x 0.8mm, and it has a 5% accuracy tolerance, meaning it will accurately regulate the input voltage source to a certain level as needed.The LT1021CCN8-5#PBF is also equipped with an on-chip trim adjust, allowing the output voltage to be trimmed with the aid of external resistor. This adjustability makes the LT1021CCN8-5#PBF suitable for a variety of applications that require voltage stability, such as in precision calibration instruments, digital-to-analog converters, microprocessor power management systems and automotive systems.The LT1021CCN8-5#PBF is powered by a single voltage source, connected to the pin designated for VCC, between 4.75V and 20V (depending on temperature range). The input voltage is then regulated to a stable output voltage, as determined by a resistor divider, connected to the VOUT and ADJ pins. When configured in the typical application circuit, the LT1021CCN8-5#PBF output voltage is a stable reference supply and independent of temperature, load current and input voltage variations.The LT1021CCN8-5#PBF is capable of delivering up to ± 5mA of sourcing and sinking currents, providing stable voltage outputs. Furthermore, its wide common-mode input voltage range of 3V to 13V enables it to be used as a general-purpose amplifier with low offsets and low noise Figure of Merit (FOM) of only 70 μA pA/V.In terms of performance, the LT1021CCN8-5#PBF provides an extremely stable reference voltage of up to ±75 ppm/°C (typical) over the entire temperature range (−40°C to 125°C) with outstanding line and load regulation. Its dynamic response time is less than 1 μs and its current consumption is less than 10 μA. In addition, its high input impedance allows it to be used in high-side current sensing applications with low dropout voltage for improved signal-to-noise ratios.Overall, the LT1021CCN8-5#PBF offers designers a high performance voltage reference device, which is robust and offers accuracy, precision, and low power consumption. It is suitable for a wide range of precision calibration instruments and power management applications, where accuracy and stability of the output voltage is critical.
