The AP2204R-3.3TRG1 is a high-grade linear voltage regulator ideal for use as an input voltage source for precision analog circuits. It has a wide input range (1.65V to 5.5V) and features accurate voltage regulation down to 0.25% over-voltage or under-voltage. It also has a high-performance Bias Voltage FET ensuring a clean, noise-free output signal.

In terms of applications, this voltage regulator is ideally suited for use in applications such as medical equipment, test and measurement equipment, and precise motion control systems. It can also be used in power supply and electroplating applications.

Regarding its working principle, the AP2204R-3.3TRG1 utilizes a P-channel non-conductive layer MOSFET (NFET) to provide precise voltage regulation. When the input voltage exceeds its set value, the NFET decreases its conductivity, preventing the voltage from rising beyond the set point. Likewise, when the input voltage falls below its set value, the NFET increases its conductivity, preventing the voltage from dropping to dangerously low levels.

This voltage regulator combines an exceptionally precise voltage regulation circuit with an ultra-low-noise MOSFET. The NFET is designed to reduce or eliminate switching noise or “beat” frequencies, making it extremely suitable for use alongside sensitive analog circuits.

As a final note, the AP2204R-3.3TRG1 features short-circuit and over-current protection. It also features low-noise operation and a low-dropout voltage, making it a great choice for applications requiring a highly reliable, stable output voltage.
