PF5200

The PF5200 is a high-efficiency, low-dropout linear regulator (LDO) manufactured by NXP Semiconductors, designed for powering sensitive analog and mixed-signal circuits in portable and battery-operated devices. It features an ultra-low quiescent current of typically 1.5 µA, making it ideal for applications where power consumption must be minimized during standby or sleep modes. The device supports an input voltage range from 1.8 V to 5.5 V, allowing compatibility with various power sources including single-cell lithium-ion batteries and standard 3.3 V or 5 V systems. This LDO delivers a stable output voltage with excellent line and load regulation—typically less than 2 mV under varying conditions—ensuring reliable performance even under dynamic load changes. Its low dropout voltage of just 120 mV at 100 mA enables efficient operation near the input supply, maximizing battery life. The PF5200 also incorporates comprehensive protection features such as over-current protection (OCP), thermal shutdown, and reverse battery protection, enhancing system robustness and reliability in harsh environments. Designed for compact applications, the PF5200 is available in a space-saving 2 mm × 2 mm WLCSP package, which reduces board footprint while maintaining excellent thermal performance. It is optimized for use in mobile phones, wearables, IoT sensors, and other portable electronics that require clean, stable power rails for microcontrollers, RF transceivers, and analog front-ends. The device operates reliably across a wide temperature range from -40°C to +125°C, making it suitable for industrial and automotive-grade applications. With its combination of high efficiency, minimal quiescent current, integrated protections, and small form factor, the PF5200 provides a robust and energy-efficient solution for modern electronic systems demanding precision power management in space-constrained designs.
