The ADP162ACBZ-2.8-R7 is a low dropout linear voltage regulator manufactured by ON Semiconductor. This device provides a regulated output voltage of 2.8 volts. The input voltage range for the ADP162ACBZ-2.8-R7 is from 2.9 to 6.0 volts, and it offers a maximum output current of 120mA.

The ADP162ACBZ-2.8-R7 is primarily designed for use in portable and handheld electronic devices, such as smart phones and tablets, where a stable voltage source is necessary. It is particularly suited for applications that need to run on a battery and are sensitive to rapid changes in the battery voltage, requiring a high degree of electrical regulation. The 2.8volt output and 120mA current limit make it well suited for portable applications, as well as general-purpose voltage regulation and low-dropout performance.

The ADP162ACBZ-2.8-R7 features a low dropout voltage of 160mV. This feature allows the device to continue providing a stable output voltage even when the input voltage is close to the output voltage. Additionally, the device is capable of operating with a wide range of temperatures, from -40°C to +125°C. The ADP162ACBZ-2.8-R7 also features a wide range of protections, including over-current, thermal shutdown and reverse-battery protection.

The ADP162ACBZ-2.8-R7 offers an extremely low total quiescent current of 35μA and a low output noise level of 40μVrms. Additionally, it provides excellent transient response with a minimum of 1.2μs settling time to within 0.25% of its final value after a sudden load step. This ensures a stable output voltage even when the load changes rapidly.

The working principle of the ADP162ACBZ-2.8-R7 is based on the classic series linear regulator topology. The output voltage is controlled by the input voltage (Vin) and a reference voltage (Vref). The voltage regulation occurs through the internal transistor, which serves as a variable resistor. As Vin increases, the transistor senses the change in voltage and adjusts its resistance to maintain the output voltage (Vout) at the desired level.

The ADP162ACBZ-2.8-R7 includes a bandgap reference, which is a temperature-independent reference voltage source. It is the ideal solution for applications that require a wide temperature range and tight voltage regulation. The reference voltage (Vref) is compared against the input voltage (Vin) to ensure that the output voltage (Vout) remains constant. Additionally, the device includes current limiting protection, which helps protect the device in the event of unexpected high amount of current being drawn.

The ADP162ACBZ-2.8-R7 is an ideal solution for portable or handheld electronic devices and other applications where a low dropout voltage and high-performance voltage regulation is required. Its low power consumption, wide operating temperature range, and extensive set of features make it a great choice for designers looking for a reliable and cost-effective solution.
