PQ025EZ02ZPH Integrated Circuits (ICs)

Sinopower PQ025EZ02ZPH, a linear voltage regulator, belongs to Sinopower PMIC series. Apart from providing a variety of convenient features, it offers superior performance, remarkably low power consumption and excellent transient response characteristics.

It is a three terminal, adjustable linear voltage regulator with a 1.225V reference voltage integrated into the chip. An external capacitor is used to adjust the output voltage. Its typical application conditions are 4.5V-28V input voltage and 0.6V-1.8V output voltage range.

The on-chip reference voltage is 1.225V and the output voltage set voltage is 0.95V-Vin. It also provides three terminals (GND, Bypass, and Output) for control. The Bypass terminal has an internal 30mA output current limit, and an external pull-up resistor is required when setting the output voltage.

PQ025EZ02ZPH has many features that make it stand out. Its low minimum operating voltage is 4.5V, it can provide output voltages down to 0.8V, and it features excellent transient response characteristics. It also has a built-in thermal and current protection, as well as an internal soft start.

In addition, the PQ025EZ02ZPH has a very low power consumption. Its quiescent current is at 30μA(typ) max and its shutdown current is at 0.01μA(typ.) max. The chip also utilizes an advanced biasing and power supply circuitry, which makes it highly efficient.

In terms of applications, the PQ025EZ02ZPH is suitable for use in a variety of consumer electronics, automotive and industrial applications. It can be used in consumer electronics such as LED lighting systems, digital TV, LED backlighting and portable digital devices. It can be used in automotive applications such as power controllers, DC/DC converters, and motor controllers. It can also be used in industrial applications such as PLCs, touch panels, and medical devices.

The working principle of the PQ025EZ02ZPH is simple. The output voltage is set with a voltage reference on the chip and an external capacitor connected to the bypass terminal. The voltage reference voltage ranges from 0.95V to the input voltage. When the output voltage reaches the set voltage, the output current is regulated and the bypass voltage is maintained.

In summary, the PQ025EZ02ZPH is a highly capable and reliable three-terminal linear voltage regulator from Sinopower. It offers a wide range of features, excellent performance, superb power efficiency and low noise levels. It is perfectly suited for a variety of consumer electronics, automotive, and industrial applications.
