What is AZ78L05HTR-G1?

AZ78L05HTR-G1 is an adjustable linear voltage regulator manufactured byAZlo Electronics. It is classified as a PMIC (power management integrated circuit), more specifically a Voltage Regulator of the Linear type. The AZ78L05HTR-G1 is an integrated device with a single input voltage, providing a stable output voltage to the load. It features an on-chip power-on reset circuit, over-power protection, full current limiting, and thermal protection. Overall, the AZ78L05HTR-G1 is a reliable, low-cost voltage regulator solution for many applications.

Application Fields

The AZ78L05HTR-G1 is suitable for a variety of applications, both consumer and industrial. It can be found in battery-powered devices, cell phones, portable navigation systems, and industrial measurement applications. AZ78L05HTR-G1 can act as intermediary devices between various power sources, such as AC/DC converter, DC-DC converter, battery, or even solar panels. This makes it well suitable for stand-alone power supplies or even in an industrial setting with multiple power sources.

In addition to the abovementioned applications, AZ78L05HTR-G1 can also be used for voltage regulation with microprocessors and DSPs in automotive and other motor control applications. It also serves as a reference power for logic circuits, as well as for driving smaller loads in consumer and industrial products.

Working Principle

The AZ78L05HTR-G1 is a two terminal adjustable voltage regulator, capable of providing up to 500mA of current to the load. It features an on-chip error amplifier, regulation comparator and a voltage divider, allowing it to accurately regulate the output voltage. The output voltage is adjusted with two external resistors, while the input voltage must remain in the range of 1.8 to 5.5V.

The AZ78L05HTR-G1 features a current-limit circuit that limits the current to the load depending on the input voltage. This is important for high current loads and in the event of an overcurrent condition, the current limit will start limiting the current. This current-limit circuit, combined with the over-temperature protection, ensures maximum safety and reliability in colder environments.

Overall, the AZ78L05HTR-G1 is a low-cost solution for many applications as it is able to deliver a stable voltage to the load. It is suitable for both consumer and industrial applications, and is able to perform in colder environments due to its current- and temperature-limiting capabilities.
