The PQ1X451M2ZP is a high power, low drop-out linear voltage regulator. It is part of the PQ1Xvoltage regulator family, offering a maximum output voltage of 16.0 V, a maximum input voltage of 19.2 V, and a typical drop-out voltage of 0.45 V at 1 A. It is designed to provide a cost-effective solution that is both reliable and efficient.The PQ1X451M2ZP is a low drop-out (LDO) linear voltage regulator that features a low noise output, a wide operating temperature range (from -40°C to 125°C), and a maximum current rating of 1 A. It is ideal for automotive, industrial and communication applications. It also offers protection against over-current, over-voltage and overtemperature conditions.The regulator is designed to maintain a constant output voltage despite input voltage fluctuations. It achieves this by using a series of transistors and resistors that act as a voltage reference. When the input voltage is higher than the set output voltage, a transistor is turned on. This allows current to flow, pulling down the voltage to the desired level. When the input voltage is lower than the set output voltage, a transistor is turned off, stopping current flow. This allows the voltage to rise until it reaches its set level. This method is referred to as “linear regulation.”The PQ1X451M2ZP is designed to provide high power, low drop-out voltage regulation for automotive, industrial, and communication applications. It features low noise output, wide temperature range operation, and 1 A maximum current rating. Its linear regulation method helps to ensure reliable, consistent voltage regulation over a range of input voltage levels. This makes the PQ1X451M2ZP ideal for applications where accurate, reliable voltage regulation is needed.
