Categories: Linear, Low Drop Out (LDO) Regulators
Quality Control: Learn More
The National Semiconductor LP2982IM5-4-5 is a positive fixed output voltage linear regulator IC. This LDO regulator provides a stable 4.5V output with a maximum output current of 50mA. It features a low quiescent current of 95 µA and a high PSRR of 45dB at 1kHz, making it suitable for noise-sensitive applications. The device operates from an input voltage range up to 16V and exhibits a low dropout voltage of typically 0.325V at 80mA. Protection features include over current, over temperature, and short circuit protection. The LP2982IM5-4-5 is supplied in a TSOT-23-5 package, designed for surface mounting. This component is commonly found in portable electronics, battery-powered devices, and automotive applications requiring efficient voltage regulation.
