The ADP7105ARDZ-5.0 is a linear voltage regulator within the power management integrated circuits (PMIC) category. This regulator is designed to provide adjustable, low noise, low dropout voltage regulation of both positive and negative voltages. The device is designed to offer a very high level of integration including fast over-voltage protection, adjustable current limit, power good, active discharge, exposed/thermal pad, and over-temperature protection.

The ADP7105ARDZ-5.0 provides a highly efficient and programmable solution for regulating voltages from 0.8V to 5V. The device can deliver a maximum load current of up to 10A, enabling it to be used in a wide variety of applications. These applications range from simple power regulation functions in consumer electronics, to power switching and current regulation in automotive and industrial applications.

This linear regulator has an input voltage range of 2.5 to 26V and an adjustable output voltage range of 0.6V to 5.0V. It is designed to operate with a minimum of stress on the input voltage and draw a significantly lower quiescent current than traditional linear regulators. The quiescent current of the device is typically only 350μA in adjustable regulation mode and 1.8mA in over-current protection mode.

The device consists of current limit, over-temperature protection and power good monitoring circuit. Its thermal protection feature prevents damage to the device by disabling the output voltage when the junction temperature exceeds 150°C. This feature enables the device to be used in a wide variety of thermal environments. The device also provides an adjustable over-current threshold which is can be programmed by external resistors. Additionally, the device features a power good and active discharge pins which allow the device to provide a signal to the system when the output voltage exceeds the specified voltage.

The device operates with a very low dropout voltage, typically less than 0.5V at low load current, while at maximum (10A) output, the dropout voltage is only 0.8V, resulting in higher efficiency and higher power delivery. It is also designed to provide a very stable output voltage, with a typical ripple rejection of 56dB.

Overall, the ADP7105ARDZ-5.0 is an ideal solution for a wide variety of applications which require low noise, low dropout, and regulated power. The device provides an efficient and highly integrated design, and its adjustable current limit, power good monitoring, over-temperature protection, and active discharge pins make it suitable for many types of power management applications. As such, the device can provide reliable and durable performance in any application.
