AP2122AK-3.2TRE1 is a linear voltage regulator manufactured by ANPEC Electronics Corporation specifically designed for the power management of electronic circuits. It is ideal for applications where low power consumption and excellent energy efficiency are needed. The device features wide operating temperature ranges from -40 to +85°C and is capable of controlling up to 3A loads. Additionally, it includes thermal protection and current limiter to protect against over-current conditions.

The AP2122AK-3.2TRE1 regulator operates on an input voltage of 3.3V and provides a fixed output voltage of 3.2V. Its switching frequency is 700kHz and the quiescent current is 10uA. The maximum output current is 3A and a typical dropout voltage of 0.4V. The device is available in SOT89-6L package which is a compact, low-profile solution that fits perfectly into circuits requiring small size components.

AP2122AK-3.2TRE1 can be used in various application fields, including industrial control, HVAC systems, automotive electronics, security systems, and so on. It is ideal for powering point-of-load converters, SMPS, as well as voltage-sensitive or current-demanding circuits. This device also has excellent transient response, ensuring that the output remains stable even in the event of sudden power surges or short-term outages.

The working principle behind this voltage regulator is the same as for any standard linear design. It includes a pass element circuit which consists of two transistors, two resistors and two capacitors, as well as feedback circuitry. The input voltage is fed to the pass element circuit where it is regulated according to the resistance of the two transistors. The regulated output voltage is then fed through the feedback circuitry, where it is compared with a reference voltage and the two voltage signals are either added or subtracted, depending on their respective regulatory condition. The resulting correction signal is then sent to the pass element circuit, where it is amplified and used to adjust the output voltage accordingly.

The AP2122AK-3.2TRE1 linear voltage regulator is a reliable, easy to use and cost-effective solution to the power management needs of electronic circuits. Its advanced features and long operating temperature range make it suitable for a wide range of applications and its small size makes it easy to integrate into even the most compact electronic design. Whether you are looking for a high performance regulator or one with low power consumption, this regulator can provide the solution you need.
