PQ1K303M2ZPH Integrated Circuits (ICs)

PMIC - Voltage Regulators - Linear

The PQ1K303M2ZPH is an advanced Linear Voltage Regulator (LVR) developed to manage power delivery in high-performance consumer electronics and industrial devices. It functions as an active voltage regulator, converting an input voltage to a regulated output. It is used to convert a DC voltage to a lower DC voltage. This device contains a regulator circuit and features a soft-start and remote shutdown capability. It is a low-noise voltage management solution created to manage low and ultra-low currents.

This device is designed to provide very low output noise, low output drop and fast transient response. A traditional Linear Voltage Regulator (LVR) functions by connecting the negative terminal of a power supply to the powered device, followed by a pass transistor. The Regulator adjusts the voltage by dynamically adjusting the on/off state of the pass transistor. By using this technique, the device can maintain a constant precisely regulated output voltage, despite fluctuations in the input voltage.

When supplying power to a load, the LVR not only manages the voltage level, but also provides current limiting protection against over current conditions. The device also includes a thermal shutdown feature, which will shut down the device when the current exceeds a predefined value. This helps to protect the device from damage due to excessive current. The built-in adjustable soft-start feature helps to prevent inrush current during start-up and prevents large current transients.

The device supports the flexibility of an adjustable output voltage. It has three pins for setting output voltage, including a VDD pin for powering the regulator circuit, an ADJ pin for setting the output voltage, and an EN pin for enabling or disabling the device. A good choice of fixed voltage versions is available with voltages ranging from 0.8V to 5.5V. The low power consumption makes this device a good choice for battery powered applications.

The PQ1K303M2ZPH is designed for applications requiring low power consumption and high precision output voltage regulation in a wide variety of consumer electronics devices, such as digital cameras, mobile phones, and portable media players. The device is RoHS compliant and available in the small SON-5 package size, making it suitable for space-constrained applications.

As one of the most widely used Linear Voltage Regulators, the PQ1K303M2ZPH is an ideal choice for devices and applications requiring low power consumption and precision voltage regulation. With its low noise, fast transient response, and adjustable output voltage, it offers reliable power management and enhanced performance in a wide range of consumer and industrial devices.
