LM3490IM5-5.0/NOPB TI Linear Regulator | SOT-23-5 | 5.0V Output, 100mA

Product Overview

The LM3490IM5-5.0/NOPB is a fixed-output, low-dropout (LDO) linear voltage regulator from Texas Instruments. It provides a stable 5.0V output with a maximum output current of 100mA. Housed in a compact SOT-23-5 package, this device is ideal for space-constrained applications requiring low noise and high ripple rejection. The LM3490 features a low dropout voltage of typically 0.6V at full load, enabling efficient operation even when the input voltage is close to the output. It also includes internal current limiting and thermal shutdown protection.
