AP2202K-3.3TRE1

AP2202K-3.3TRE1 is a less-realized linear voltage regulator specifically designed for medium to low-power applications. It is usually used in electronic systems where the input voltage (Vin) is much grater than the desired output voltage (Vout). In these cases, this type of voltage regulator is most suitable due to its low power dissipation, low noise and high accuracy performance.

The working principle of AP2202K-3.3TRE1 is simple. It uses an external power source to create an internal voltage reference and then compares this voltage to a feedback voltage. If the voltage applied to the input terminal is greater than the voltage reference, current is drawn to reduce the output voltage until the two voltages are equivalent. When the two voltages are equal, the power is shut off, signaling that the regulator is operating correctly.

AP2202K-3.3TRE1 is especially useful in portable equipment with a strict power budget. Its low quiescent current (<0.6mA) makes it an ideal choice for battery-powered applications while its load regulation of ±0.8% helps maintain constant output voltages in wide load ranges. In addition, its wide input voltage range of 4.5V~10V supports various power sources.

AP2202K-3.3TRE1 can also be used in digital system design where noise is an important factor. Its low noise of 46µV (RMS and peak-to-peak) makes it possible to ensure the reliability and stability of digital systems. Moreover, possessing the over-current protection and low dropout voltage characteristics, it can effectively prevent device overload and ensure system safety.

Typically, AP2202K-3.3TRE1 can be applied in automotive electronics, industrial system, digital system, micro-controller systems and etc. With its constant voltage/current output, low quiescent current and low noise, this linear voltage regulator becomes a reliable and suitable solution for medium to low-power applications
