PQ1K253M2ZP is an ultra low quiescent current, low noise, low dropout (LDO) linear voltage regulator that offers excellent performance in terms of low quiescent current and low dropout voltage. This voltage regulator is suitable for mobile phones, personal digital assistants (PDAs) and other portable electronics applications.

This LDO delivers a regulated output of 1.2V to 4.5V. With its ultra-low, 0.2μA quiescent current and 0.2Ω dropout voltage, it offers the most efficient system power solutions in a wide variety of battery-powered products. Moreover, the PQ1K253M2ZP supports current up to 100mA, making it an ideal choice for applications with a wide range of power requirements. Additionally, the low-noise, low-dropout performance and high-efficient switching regulator provides higher efficiency and reduces energy consumption and battery charge cycles.

The PQ1K253M2ZP uses a PMOSFET pass element and PMOS-controlled bipolar feedback loop, together with an internal current sense FET, makes it ideal for low-noise and low-power applications. The voltage regulation circuitry of this LDO is designed with a unique architecture for fast transient response, clean output and low output voltage ripple. The PQ1K253M2ZP has an input voltage range from 2.5V to 5.5V and an adjustable version with a range of 1.8V to 5.5V. Additionally, the SHDN/EN pin of this LDO allows the regulator to be shut down and the output to be turned off. The PQ1K253M2ZP has a wide ambient temperature range of -40°C to +125°C and can be operated with minimum headroom to reduce total system power dissipation. The maximum operating junction temperature of this LDO is 175°C.

The PQ1K253M2ZP is designed with a variety of high performance features including over-current protection and thermal shutdown. The over-current protection feature protects the LDO from large output current when the output is short-circuited or the output current of the device exceeds a certain level. It automatically turns the regulator off if the output current goes beyond the predefined limit. The thermal shutdown feature of this regulator shuts the device down if the temperature exceeds a certain point to protect the device from damage due to excessive temperature.

The PQ1K253M2ZP is ideal for applications in a wide variety of handheld and portable electronic devices such as smartphones, tablets, personal digital assistants, digital cameras, navigation equipment, and other battery-powered consumer electronics.

In conclusion, the PQ1K253M2ZP is an ultra low quiescent current, low noise, low dropout voltage linear voltage regulator suitable for applications in a wide variety of portable electronics. With its low quiescent current, low dropout voltage, high efficiency and low output ripple, it offers the most efficient power solutions for the battery-powered consumer electronics. It also features several protection features such as over-current and thermal shutdown to protect the device from damage caused by excessive current or temperature.
