ADP7156ARDZ-1.2-R7 is a linear voltage regulator from the PMIC (Power Management Integrated Circuit) family. It is designed to reduce output voltage from a higher DC input voltage to a required level. This step-down type voltage regulator has a wide range of application, making it a popular choice for many industrial and consumer electronics.The device can be used for regulating low current with very low voltage and low noise. It is a single output linear regulator which can control an input voltage from either zero to maximum of 80V. This enables it to be used in circuits like automotive, communications, industrial equipment, soldering equipment, and so on.The ADP7156ARDZ-1.2-R7 can deliver a maximum of 1.2 A of continuous output current and a maximum of 5 A peak output current. The device also supports two operating modes: Buck Mode and Buck-Boost Mode. The Buck Mode is a manual toggle function where the regulator will step down the load voltage when the load current is below 1 A. The Buck-Boost Mode is a fixed voltage-controlled function that can be used to set the desired load voltage.At the input, the regulator accepts a wide range of voltages from 0-80V, extending its application range beyond traditional PWM type regulators. It also has under voltage lockout and over voltage protection, further widening its range of applications. The internal architecture of the ADP7156ARDZ-1.2-R7 is a series pass topology commonly used in linear voltage regulators. It employs a MOSFET device as the series pass transistor and sense electronics to provide current limiting, over voltage protection and other features. The input is fed through a series MOSFET and pass voltage to the output as determined by the reference voltage. This reference voltage is generated by a feedback circuit running from the output of the regulator to the input. The voltage regulator will continuously monitor its output voltage and adjust the MOSFET switching frequency accordingly to keep its output steady.ADP7156ARDZ-1.2-R7 is an excellent choice for a single output voltage regulator requirement where low noise, wide operating temperature range and economical cost are the main focus. With its wide range of application and reliable performance, it has become a popular choice for industrial and consumer electronics.
