Evaluation Boards - Linear Voltage Regulators

The ADP121CB-3.3-EVALZ is an evaluation board for the ADP121 linear voltage regulator. It is a small, low-profile board designed for easy evaluation and testing of the regulator in diverse applications. This evaluation board has been designed for applications where low dropout voltage and low quiescent current are desired, featuring a current limit feature and short circuit protection.

The ADP121CB-3.3-EVALZ is suitable for many different power supplies including automotive, telecommunications, portable electronics, industrial, computing, automotive and general purpose applications. It provides adjustable outputs up to 3.3V, with a peak current capability of 250mA. It supports a wide input voltage range from 5V to 18V with adjustable outputcurrent from 5mA to 250mA.

The device features a low-profile UL94-V0 rated package with a 15-lead dual-in-line-package (DIP) for easy integration into most applications. The ADP121CB-3.3-EVALZ Evaluation Board allows users to evaluate the ADP121 linear voltage regulator in a range of different conditions, providing various external components to allow the user to adjust voltage regulator line regulation, loop compensation, overcurrent protection, rate of rise and dropout characteristics.

The ADP121 is a linear voltage regulator with an integrated power MOSFET that reduces power loss. This makes it ideal for applications that require a low dropout voltage and low quiescent current. It also provides overcurrent protection, thermal protection, and a maximum output current of 250mA. When used in conjunction with a low quiescent current low dropout regulator such as the ADP121CB, it can provide low power and low cost power supply solutions compared to other regulators.

The ADP121CB-3.3-EVALZ evaluation board also includes all the necessary components for the ADP121 linear voltage regulator to be connected and used. The board contains the input circuitry, output regulation and fault detection circuitry, clock and reset circuits, and the output stage with its protection functionality. It includes a surface-mount resistor for setting the output voltage, an adjustable low dropout (LDO) regulator for setting the line regulation, and two 10μF ceramic capacitors for setting the output loop stability.

In addition to providing a good solution for low dropout voltage and low quiescent current applications, the ADP121CB-3.3-EVALZ also offers protection against thermal and overcurrent faults. It features output short circuit protection, overcurrent protection, and thermal protection. The overcurrent protection feature provides a hysteresis loop for output current limit-less than 250mA, the thermal protection feature limits the maximum die temperature, and the fault protection feature trips if the output voltage is shorted to ground or output is over current again and again.

The ADP121CB-3.3-EVALZ evaluation board provides an easy and reliable way to evaluate and test the ADP121 linear voltage regulator for a variety of applications. It provides flexibility in setting the desired output voltage and loop compensation, and robust protection features for enhanced reliability in the field. The integrated power MOSFET also reduces power loss and provides an efficient, low cost power supply solution.
