Introduction to ADP121-ACBZ28R7

The ADP121-ACBZ28R7 is a low-dropout (LDO) linear regulator from a new family of devices, specifically designed for applications that require either high power supply current or high output voltage accuracy. This device offers comprehensive protection and high accuracy in the highly competitive, low Vout space.The ADP121-ACBZ28R7 is a high-performance, high-density, adjustable-output, single-voltage linear voltage regulator. This device is ideal for applications such as FPGA, DSP, and ASIC supply application. It is also suitable for powering devices requiring high current with low minimum input-output voltage in the industrial, telecom and automotive markets.

Application Field and Working Principle

The ADP121-ACBZ28R7 is designed to provide DC power to complex system designs that require extreme power supply accuracy, low voltage dropout, and high power efficiency. With its extremely low total harmonic distortion, the device is capable of supplying clean power over a wide input voltage range and with high accuracy.The ADP121-ACBZ28R7 is capable of regulating both high voltage and low voltage outputs up to 56 volts. It can supply up to 800mA of continuous output current, which makes it an ideal solution for a wide range of DC-DC applications.The device is a low dropout, low frequency linear voltage regulator with a feedback circuit. When the input voltage is applied to the device, it is compared to the reference voltage. This difference is amplified by an internal error amplifier, and the output voltage is then regulated through an integrated control circuitry. The control circuit acts as a linear follower of the amplifier error signal, and the output is regulated by adjusting the gate of a linear pass element.In order to reduce power dissipation, the ADP121-ACBZ28R7 has two operating modes, low power and high power. When the current demand is low, the device choices Low Power mode, in which the output voltage is regulated by automatically turning the pass transistor on and off. When the current demand is high, the device switches to its High Power mode, which runs continuously and dynamically adjusts the output voltage to maintain a constant Vout.
