Linear & Switching Voltage Regulators

LP3876ES-5.0/NOPB Description

The LP3876ES-5.0/NOPB is a high-performance linear regulator designed for applications requiring a stable 5V output at up to 3A. Manufactured by Texas Instruments, this regulator is part of the Power Management Integrated Circuits (PMIC) category and is housed in a surface-mount DDPak/TO263-5 package. It features a fixed output voltage of 5V and an input voltage range up to 7V, ensuring reliable operation in various power supply scenarios. The regulator boasts a low dropout voltage of 1.2V at full load, which enhances efficiency and reduces power dissipation. With a quiescent current of just 5 mA and a supply current of 15 mA, the LP3876ES-5.0/NOPB is optimized for low-power applications. It also includes an enable control feature and comprehensive protection mechanisms such as over-current, over-temperature, and short-circuit protection, ensuring robust and safe operation.
