Linear voltage regulators provide a convenient way to control the output voltage of a power supply. The MPQ2019GN is a low drop-out (LDO) linear voltage regulator designed to deliver up to 1.5 Amps of load current. It is designed to offer a wide input voltage range, low dropout voltage and low noise operation.

The MPQ2019GN is a surface mount device with an input voltage range of 2.5V to 25V, and is capable of output voltage range from 0.8V to 20V. The output regulation is ± 1.5mV, in 1% increments. The MPQ2019GN has a minimum input/output differential voltage of 0.25V which is relatively low compared to other LDO regulators. This makes it suitable for applications where the input and output voltage is close together.

The MPQ2019GN features thermal protection, reverse polarity and over-current protection, making it ideal for use in portable applications. It is available in the SOT-223 and Micro-8 packages, making it very versatile in terms of physical size. The device is highly efficient due to its low quiescent current and large energy storage capacitor.

The MPQ2019GN offers high performance, low noise, and good accuracy. Its output voltage can be adjusted both electronically and manually. The device is rated for operation up to 150°C, and has no need for external cooling. It offers excellent transient response and good long-term line and load regulation, making it ideal for critical power applications.

The MPQ2019GN is commonly used for regulating voltage in low power DC-DC converters and other power supplies, such as in digital signs, PCs, cell phones and other wireless communication devices. It can also be used in battery powered and automotive applications. Other applications include home security systems, industrial and test equipment, power tools, and medical electronics.

The MPQ2019GN offers a high level of protection to the power supply system and components due to the inclusion of integrated protection features. It is able to self-regulate its output voltage, allowing the device to automatically adjust overclocking and overvoltaging, as well as providing self-resetting to prevent permanent damage. The device also provides short circuit protection, as well as reverse polarity and inrush current protection, ensuring the power supply is safe from overload and overvoltage.

In summary, the MPQ2019GN is a highly reliable, cost effective, and efficient voltage regulator for a range of power supply applications. It features low dropout voltage, excellent transient response, electronic and manual adjustable output voltage, and integrated protection features. It is highly versatile, available in different packages, and is suitable for use in automotive, low power DC-DC converters and other power supplies.
