LM4050BIM3-5.0/NOPB – TEXAS INSTRUMENTS

The Texas Instruments LM4050BIM3-5.0/NOPB is a low-dropout (LDO) voltage regulator in a compact 4-pin SOT-23-5 (3x3mm) surface-mount package, featuring lead-free, RoHS-compliant construction. Specifically designed for low-noise, high-efficiency applications, it provides a fixed 5.0V output voltage with a typical input voltage range of 5.5V to 16V. The device boasts a very low quiescent current of typically 10µA, making it ideal for battery-powered systems. Its output current capability is specified at 500mA, though peak currents may be higher depending on thermal considerations._x000D_

The LM4050BIM3-5.0/NOPB incorporates thermal shutdown and short-circuit protection features, enhancing system reliability. Its low output noise of typically 30µVrms ensures clean power for sensitive analog circuits. Common applications include powering microcontrollers, digital-to-analog converters (DACs), and other low-power peripherals where a stable 5V supply is required. Its small size and high efficiency make it particularly advantageous in space-constrained designs where minimizing power loss and PCB footprint are critical. The absence of an enable pin simplifies design integration. Note the absence of overvoltage protection; external circuitry might be required in applications with potential over-voltage events.
