The integrated circuit, NCV8502PDW100R2G, is a low drop-out (LDO) linear voltage regulator. It is classified as a PMIC (power management integrated circuit) and as a voltage regulator in a linear regulator family. It is marketed by ON Semiconductor and is widely used in different industries and consumer device applications such as portable consumer devices, automotive and communications.

The NCV8502PDW100R2G is mainly used to supply a fixed output voltage from a higher input voltage when the load needs are low. The power supply current from input to output is extremely low, so it can be used as a low power supply current regulator. Low power DC-DC step down regulating is another application for the NCV8502PDW100R2G – it is an ideal solution for powering small low-power devices.

The main features of the NCV8502PDW100R2G are its functionality, stability, and protection features. It is exceptionally simple and efficient to use and appears as a 4-pin Typepackage. It is designed to provide a stable 3.3V output voltage from a 2.6V to 6V input voltage range. It also includes internal current limiting, thermal shutdown, and reverse polarity protection. The high power output and very low quiescent current make it an ideal solution for medium power applications. The output voltage accuracy is ±2.0%, while the maximum load current is 100mA, and the operating temperature range is from -40°C to 85°C.

The operation of the NCV8502PDW100R2G is pretty straightforward. Firstly, the input voltage is sensed and compared with the internally-set reference voltage. Then, the error amplifier increases the current in the voltage sampling resistor, which is connected to the adjustment terminal of the device. After this, the voltage at the adjustment terminal sets the output voltage. The output is then made available from the output pin to the required load. Finally, the feedback loop monitors the output voltage continuously, and it is regulated by adjusting the current.

So, the NCV8502PDW100R2G is an ideal low drop-out voltage regulator with robust features like protection, low power requirements and high efficiency for low current applications. It is especially suitable for applications where there is a need to regulate an input voltage source down to a desirable output voltage level. Additionally, its adjustable output voltage allows further fine tuning of the circuit design. Thanks to this, simple and straightforward solutions to voltage problems can easily be constructed with the NCV8502PDW100R2G.
