Evaluation Boards - Linear Voltage Regulators

ADM7154RD-1.8EVALZ is a high performance linear voltage regulator evaluation board that is designed to support performance evaluation for the ADM7154RD-1.8 and ADM7154BD-1.8 low dropout (LDO) voltage regulators. It offers adjustable output voltage options ranging from 1.8V to 2.44V with a low 0.06 Ohm output impedance. This evaluation board was developed to support the development of digital circuits, such as mobile phones and PDAs, as well as the testing of robots, motion video processing systems, communication systems, and industrial automation systems.

The ADM7154RD-1.8EVALZ evaluation board is built with a four-layer, copper-clad PCB and a non-inverting three-terminal linear regulator for improved efficiency. It is designed to allow seamless operation with a wide range of input voltages from 1.3V to 3.3V. The board is equipped with an adjustable voltage divider and a 100nF bypass capacitor to provide a precise output voltage control. The board also has two LED indicators which indicate the position in the input power lines with each colour representing a specific voltage level.

The ADM7154RD-1.8EVALZ evaluation board is a bidirectional device, which comprises of a low on-resistance MOSFET switch to control the flow of current. It also contains a current-limiting circuit which protects the device from over-current conditions. When the output voltage is above a predetermined level, the current-limiting circuit acts to limit the output current to the preset value. This provides additional protection against output voltage overshoot.

The ADM7154RD-1.8EVALZ evaluation board provides a high power supply efficiency of up to 90% when working with a 5V input. It provides a fast and accurate response to output voltage changes, with a maximum transient response time of 25ms. Additionally, the board is EMI tested and verified to meet stringent noise requirements.

In summary, the ADM7154RD-1.8EVALZ evaluation board has been designed for testing, evaluating, and prototyping applications with a wide range of input voltages requiring an adjustable output voltage and high efficiency. It is an ideal solution for mobile application prototyping, industrial automation, and motion video processing.
