LP590718QDQNRQ1 TI LDO Regulator | 4-X2SON(1x1) | 250mA, 1.8V Output

Product Overview

The LP590718QDQNRQ1 is a low-dropout (LDO) linear voltage regulator from Texas Instruments, designed for automotive applications. It delivers up to 250 mA output current with a fixed output voltage of 1.8 V. Housed in a compact 4-pin X2SON package (1 mm x 1 mm), this device offers excellent line and load transient response while maintaining low quiescent current. The LP590718QDQNRQ1 is AEC-Q100 qualified, making it suitable for harsh automotive environments.
