LM3940IMPX-3.3/NOPB TI LDOs
The LM3940IMPX-3.3/NOPB is a 1A low-dropout linear regulator from Texas Instruments, specifically designed to provide a fixed 3.3V output from a 5V supply. Verify input voltage between 4.5V and 5.5V (absolute max 7.5V). Confirm dropout voltage of 310mV typical (500mV max), requiring only 4.5V minimum input for regulation. Note quiescent current of 15mA typical and fixed 3.3V output with ±2.5% accuracy. Ensure operating junction temperature from -40°C to 125°C with built-in overtemperature and short-circuit protection. Ideal for 5V to 3.3V conversion in desktop/laptop computers, logic systems, industrial automation, energy and power systems, renewable energy equipment, and applications where a single external component is desired for minimal board space.
