DPA426R-TL Integrated Circuits (ICs)

DPA426R-TL is a voltage regulator specifically designed for low-voltage, low-power applications such as microcontrollers, CPUs and DSPs. It is a special type of power management integrated circuit (PMIC) and is designed to regulate the voltage of the circuit in order to ensure stable and safe operation over a wide temperature range. The DPA426R-TL is a fixed-output, three-terminal linear regulator that requires only two external capacitors to guarantee stable and clean power supply, which makes it ideal for remote sensing applications.

The DPA426R-TL is designed to work at a voltage between 0V and 20V, with a maximum load current of 4.5A. This voltage regulator can provide a stable current while still providing low noise, low ripple and low electromagnetic interference. The output voltage of the DPA426R-TL can be set to any value within the operating range of its circuit by changing the value of the external feedback resistor. This makes it a versatile device for many applications.

The DPA426R-TL is configured to control the average current of the load and can be used for either step-down or step-up operations. In step-down mode, the DPA426R-TL will use a linear feedback system to regulate the output voltage. This is achieved by monitoring the output voltage, comparing it to the reference voltage, and adjusting the duty cycle of the internal switch to maintain the desired output voltage. In step-up mode, the DPA426R-TL acts like a current-mode step-up converter, using the internal FET switch to regulate the output voltage by directly controlling the output current.

In addition to the features mentioned above, the DPA426R-TL offers several other features that make it ideal for voltage regulator applications. It is designed to offer excellent line and load regulation, as well as EMI/RFI noise suppression. The device also features over-current protection, thermal shutdown and over-voltage protection. It is available in a wide variety of package sizes to meet the needs of various designs.

The DPA426R-TL is a highly efficient and versatile linear voltage regulator and is ideal for applications where power management, low power consumption and stable power output are essential. It is an excellent choice for voltage regulator applications in microcontrollers, CPUs and DSPs, as well as remote sensing applications. The DPA426R-TL offers superior performance and reliability and is available in a variety of package types to meet the needs of any design.
