LP38511MRX-ADJ/NOPB TI LDO Regulator | 8-SO-POWERPAD | 3A, Adj Output

Product Overview

The LP38511MRX-ADJ/NOPB is a high-performance adjustable low-dropout (LDO) linear regulator from Texas Instruments, designed to deliver up to 3A of output current with a dropout voltage of typically 280mV at full load. It operates over a wide input voltage range from 2.5V to 7V and provides an adjustable output voltage from 0.8V to 5.5V, set by external resistors. The device is housed in an 8-pin SO PowerPAD package, which enhances thermal dissipation for reliable operation in demanding applications. With excellent line and load regulation, low output noise, and fast transient response, this LDO is ideal for powering sensitive analog and digital loads in industrial, automotive, and telecommunications systems.
