Introduction to PQ1K503M2ZPH

PQ1K503M2ZPH is a type of linear voltage regulator that is suitable for use in both automotive and industrial applications. It is an advanced product from ZETEX, a well-known global company specializing in the production of circuit protection, power system management, and thermal management solutions. This device can provide up to 5A continuous output current and is designed to reduce the input voltage to an adjustable output voltage of up to 1.2V.

Application Field

PQ1K503M2ZPH can be used in a variety of automotive, industrial, and consumer applications. In automotive applications, it is used to regulate the supply voltage to electronic control units (ECUs), infotainment systems, lighting, and several other automotive components that require a regulated supply voltage. In industrial applications, it is used to regulate the input voltage to instrumentation, motor controllers, and safety equipment. It is also suitable for use in consumer electronic devices, including phones, tablets, and laptop computers, to provide an adjustable output to peripherals.

Working Principle

The PQ1K503M2ZPH linear voltage regulator works by using an integrated circuit with a series of high-efficiency transistors, resistors and capacitors. These parts act together to create a feedback loop which senses the output voltage against the reference voltage and adjusts the current and voltage in corresponding proportions to maintain the output voltage within a very narrow range. This regulator also contains built-in protection circuits, such as over-voltage and current shutoff, reverse polarity protection, and ESD protection.
