PMIC - Voltage Regulators - Linear ADP151ACBZ-2.8-R7 is a linear voltage regulator IC from Analog Devices. It is designed to supply 1.5 A output from a 2.8V to 5.5V input, a popular supply rail for many battery powered portable devices. This article will explain the application fields of ADP151ACBZ-2.8-R7 and its working principle. Application fields ADP151ACBZ-2.8-R7 is used in a wide range of applications and provides an economical and efficient solution for low voltage and low power applications, including wearable devices, medical systems, and automotive accessories. The output voltage of the linear regulator is adjustable from 1.2V to 5.5V, making it ideal for powering low voltage microcontrollers, digital signal processors, and other components used in many applications. The device is capable of achieving an efficiency up to 96%, making it suitable for longer battery life and higher efficiency applications. Another key feature of this device is its short-circuit protection and an overcurrent protection, which prevents the device from being damaged in case of an overcurrent, short circuit, or over-temperature situation. The device also includes an enable pin, allowing the regulator to be turned off in order to save power and improve battery life. Working principle The ADP151ACBZ-2.8-R7 is a linear voltage regulator. The voltage input is applied to the regulator and is compared to a reference voltage. The error amplifier output is then used to adjust the output voltage to the desired level. The output is then fed through series pass devices, which convert the error amplifier voltage into current so that it can be used to control the output voltage. The output voltage is regulated by the ratio of the input voltage, reference voltage and current sense resistors. As the input voltage drops, the difference between the input voltage and reference voltage increases, causing an increase in the output voltage. Similarly, as the input voltage rises, the difference decreases, causing the output voltage to decrease. The voltage regulator is protected by two current limiting elements—over current protection and short-circuit protection. The over current protection element ensures that the output current is not exceeded and the short-circuit protection element ensures that the output voltage remains at a safe level even in the event of a short circuit. The voltage regulator also includes thermal shutdown protection, which shuts down the device in the event of an over temperature situation. ADP151ACBZ-2.8-R7 is a linear voltage regulator that provides superior output voltage regulation and high efficiency in a small package. It is ideal for a variety of applications and provides an economical and efficient solution for low voltage and low power applications. Its features such as flexible output voltage range, excellent load regulation, low dropout voltage, low quiescent current, over current protection, and thermal shutdown protection make it the ideal choice for many designs.
