Working Principle

The working principle of NCV8501D50 linear voltage regulator is based on the outputs of two voltage amplifiers operating in the feedback loop. The output voltage is determined by comparing the feedback reference capacitor (R1) with the input voltage divided by the resistive divider, R2 and R3. The error amplifier then adjusts the gate voltage of the pass transistor to ensure the output voltage is kept stable. When the output voltage drops, the error amplifier increases the gate voltage to turn on the pass transistor to boost the output voltage.

Pin Configuration

NCV8501D50 has a SOT563-5 pin configuration. Pin1 is ground (GND), pin 2 is input (VIN), pin 3 is output (VOUT), pin 4 is feedback voltage (VFB) and pin 5 is enable (EN).

Conclusion

NCV8501D50 is a cost-effective and space saving voltage regulator designed for a range of applications in consumer electronics, automotive, and industrial markets. Its wide range of adjustable output voltage options, wide operating temperature range and excellent ripple rejection makes it suitable for a range of applications. The working principle of the regulator is based on the feedback loop principle, where the output voltage is kept stable with the help of the error amplifier and the pass transistor.
