PQ12DZ51J00H is a voltage regulator of Linear category in PMIC (Power Management Integrated Circuit). A voltage regulator can automatically maintain a constant voltage at its load, even when the input supply or load condition changes. This ensures that a load always receive a consistent voltage to operate in optimal parameters.

The PQ12DZ51J00H is designed for advanced power management applications with low dropouts and high-efficiency. This voltage regulator has a full thermal protection feature to ensure no heat generated due to normal operation. With an active low shutdown control, the device can offer an ultra-low supply current.

The PQ12DZ51J00H regulator uses two P-channel MOSFETs to control the output voltage, a voltage reference source and a few resistors to set the working current. It also includes two error amplifiers to enhance the line and load regulation. The construction of the circuit is such that the output voltage of the regulator is determined by the voltage reference, voltage drop across the sensing resistor and the current through the regulating transistor.

The PQ12DZ51J00H voltage regulator can output a regulated voltage ranging from 2.0V to 7.5V. To have a precise application, the operating temperature should be within 0°C to 75°C. The operating current for very low dropout voltage is 20mA.

The PQ12DZ51J00H can be found in applications such as audio amplifiers, high-end portable electronics, LED controllers, industrial automation, media processing and medical equipment. With an ultra-low quiescent current, wide operating temperature range, low dropout voltage and a high current output capability, the PQ12DZ51J00H is suitable to power sensitive analog and digital loads in mid-range battery operated and automotive applications.

By providing a reliable, constant output voltage, the PQ12DZ51J00H ensures stabilized and accurate current so the devices connected to it would function properly. This regulator has high power efficiency and can be effectively dissipated in the circuit, making it ideal for several power management applications.
