The AP2125KC-3.3TRG1 is a series of Voltage Regulators of Linear PMIC designed and manufactured by Diodes Incorporated. It is a reliable, low-noise linear voltage regulator that provides a stable output voltage with very low dropout voltage, wide input voltage range and low quiescent current. This device is suitable for applications requiring low-noise output voltage and operates from the input voltage rail up to 8 V with an amazing high output of 1.0A.

The AP2125KC-3.3TRG1 is available in SOT23-5L, TDFN-2L, SON-8L and UDFN-10L packages as well as other options that suit a variety of installation requirements. The device has been designed for low-voltage, low-noise, low-power and cost-effective computing, communication and portable instrumentation applications. It has many protection functions, such as over-voltage protection, over-current protection and power-good monitoring.

The internal operating voltage of AP2125KC-3.3TRG1 is based on buck topology. Internally, it contains an NMOS and PMOS FETs and a pass transistor that can be operated in buck or boost operations. The output voltage can be controlled using an external resistor divider. The external resistor divider is used to set the output voltage as well as the output current. The internal pass transistor can operate in linear or switching mode. The linear mode provides a smooth, low-noise supply with low Ripple and high efficiency. The switching mode provides higher output current and higher efficiency.

The AP2125KC-3.3TRG1 provides two main features. First it provides a voltage tracking feature that allows the output voltage to be adjusted up or down depending on the needs of the application. Second, it provides short-circuit protection that prevents the output from going over its rated current. Electronic fuses are provided to protect against over-current or short-circuit situations. In addition, the device has reverse leakage protections as well as a power-good flag.

The AP2125KC-3.3TRG1 is ideal for IoT, consumer and industrial applications that require low-noise and cost-effective power supplies. Its wide input voltage range is suitable for applications powered by a variety of sources, such as wall adapters, batteries, solar and vehicles. With its low noise operation, high efficiency and accurate output voltage control, the AP2125KC-3.3TRG1 is the perfect choice for applications with stringent requirements on power efficiency, noise, and current.
