Overview
The ADPL44002ACPZN3.3-R7 is a low-dropout linear voltage regulator manufactured by Analog Devices Inc., designed for surface-mount applications in LFCSP-6 packages. It provides a fixed 3.3V output with a maximum continuous current of 200mA. The device operates within an input voltage range of 2.7V to 40V and maintains a typical dropout voltage of 220mV at full load. Key electrical characteristics include a quiescent current of 80µA, a line regulation of 0.01%/V, and a load regulation of 0.002%/mA. It features high power supply rejection ratio (PSRR) performance of 78dB and functions reliably across an extended temperature range from -40°C to +125°C.
Feature Summary
- Fixed 3.3V output voltage configuration
- High input voltage tolerance up to 40V
- Low quiescent current operation
- Extended industrial temperature range
Applications
- Portable battery-powered equipment requiring stable 3.3V rails
- Industrial control systems operating in harsh environments
