ADP7142AUJZ-1.8-R7 Linear Regulator from Analog Devices Inc.

The ADP7142AUJZ-1.8-R7 is a high-performance CMOS linear regulator offering a very low dropout voltage and low noise, with a fast transient response. Manufactured by Analog Devices Inc., a leader in precision high-performance integrated circuits, this component is designed to deliver a fixed output voltage of 1.8V with an input voltage range from 2.7V to 20V. Its versatility makes it suitable for a wide array of applications, including sensitive RF supply circuits and high-speed analog-to-digital converters.

This linear regulator is capable of providing up to 200 mA of output current while maintaining a low dropout voltage of just 115 mV (typical) at full load. This feature enables efficient operation even when the supply voltage is very close to the output voltage, which is particularly beneficial in battery-powered devices where maximizing battery life is crucial.

The ADP7142AUJZ-1.8-R7 also boasts excellent power supply rejection ratio (PSRR) characteristics and low noise performance, producing only 9 µVrms of output noise in the 10 Hz to 100 kHz bandwidth, which is ideal for precision analog circuits. Additionally, the device includes a number of safety features such as overcurrent protection and thermal overload protection, ensuring reliable operation under various conditions.

Its compact SOT-23-5 package allows for a small footprint on the PCB, which is essential for space-constrained applications. Moreover, the part number suffix 'R7' indicates that this component is provided in a 7-inch reel, facilitating automated assembly processes for high-volume production.
