PQ120DNA1ZZH Linear Voltage Regulators is a DC-DC adjustable linear regulator. This device features a wide range of input voltage up to 24 V, with a selectable output current up to 120 mA. The output voltage is adjustable from 6 V to 24 V by hitting the selector pins. The input and output pins are integrated within the package, making it possible to build a wide range of applications in a compact and cost-effective footprint.

PQ120DNA1ZZH linear voltage regulators are designed with various capabilities and features. This device has a fail-to-safe mode, which ensures that the output voltage is always within the specified range, even upon a sudden over-current or over-voltage fault condition. It also features a built-in current auto-limiting latch to ensure excess current protection. Furthermore, the PQ120DNA1ZZH linear voltage regulator regulates input current up to 2 A, which increases the efficiency of the device and reduces power consumption.

The application field of PQ120DNA1ZZH linear voltage regulators encompasses a broad range of electronics such as motor control, automotive electronics, power supplies, industrial instrumentation, adjustable lighting, and power converters. The device is well-suited for applications such as battery-operated or wall-plug devices, DSP-based systems, or low-cost AC to DC converters.

The working principle of PQ120DNA1ZZH linear voltage regulator is a feedback control loop process. This means that the output voltage is compared against a reference voltage and the difference is rectified. The difference is then converted back to the output voltage by a control circuit that consists of an op-amp, a voltage reference, and a pulse width modulated converter. The output voltage is regulated by adjusting the duty cycle of the pulse width modulated converter, thus making the output voltage go up or down to match the desired value.

In conclusion, the PQ120DNA1ZZH Linear Voltage Regulators offer a wide range of features and capabilities, making it an excellent choice for a variety of usage scenarios. Its wide input voltage range and adjustable output current enable an array of applications in the field of motor control, automotive electronics, power supplies, and power converters. Its feedback control system provides a stable and reliable output voltage even during sudden over-current or over-voltage fault conditions.
