LP590718QDQNRQ1 Description

Short technical summary and product information.

The Texas Instruments LP590718QDQNRQ1 is a 250mA, ultra-low-noise, low-quiescent-current LDO voltage regulator designed for automotive applications. It features an input voltage range of 2.2V to 5.5V and a fixed 1.8V output.

 

This device offers excellent noise performance with less than 6.5 µVRMS of output voltage noise and high PSRR of 82 dB at 1 kHz. It includes thermal-overload and short-circuit protection, along with an enable control feature. The LP5907-Q1 series is stable with 1-µF ceramic input and output capacitors and does not require a separate noise bypass capacitor.

 

The LP590718QDQNRQ1 is supplied in a compact 4-X2SON (1x1) package, suitable for surface mounting. Its operating temperature range is -40°C to 125°C (TJ), making it ideal for demanding automotive environments.

 

Applications include ADAS cameras and radar, automotive infotainment, telematics systems, and navigation systems where low noise and stable power delivery are critical.
