A voltage reference, commonly known as a voltage regulator, is a precision voltage source that can maintain a stable voltage over a wide range of input voltages, temperature and load variations. The VRE3025AD, a precision voltage reference manufactured by Texas Instruments, is designed to provide the necessary output voltage accuracy with minimal power consumption and low system cost.The VRE3025AD is specifically designed to address the common automotive applications. This device is suitable for a variety of automotive functions, including on-board diagnostics, low dropout regulators, instrumentation circuits, and as a monitoring circuit. It is designed to accommodate input voltages up to 40V and provide regulated output voltages up to 6.5V. The device consists of two sections: Low Dropout (LDO) Regulator and Low power Reference (LPR) Voltage Reference. The Low Dropout Regulator (LDO) section is responsible for providing the regulated voltage output. Under normal operating conditions, the output voltage is maintained within a reference range of ±1.0%. The LPR section provides a reference voltage for the LDO section. It is a precision voltage reference with a droop rate of 0.05%/V. The LPR section operates from an internal 0.2V reference voltage. The output of the LPR section is adjustable to provide the desired output voltage. The VRE3025AD is designed to ensure a fast response to a sudden load step. This device is designed with an adjustable Slew Rate Control that acts as a filter to maintain the output voltage within a specific range. The VRE3025AD is designed to minimize power dissipation. Its power consumption is limited by stop current limit and low quiescent current. Its Stop Current Limit ensures the device does not dissipate too much power when the output is in high-voltage state. Its quiescent current is less than 2.5mA. This helps to minimize the heat generated by the VRE3025AD compared to other voltage regulators.The VRE3025AD is a versatile voltage regulator designed to provide reliable and stable voltage supply in automotive applications. Its fast response and low power dissipation make it an ideal choice for a variety of automotive functions. With its wide operating range, low cost and high accuracy, the VRE3025AD is one of the best voltage regulators available.
