The Texas Instruments LP590745QDQNRQ1 is a 250mA, ultra-low-noise, low-IQ LDO voltage regulator designed for automotive applications. It offers a fixed output voltage of 4.5V and operates within an input voltage range of 2.2V to 5.5V.
This LDO is engineered to meet the demands of RF and analog circuits, providing excellent noise performance (< 6.5 µVRMS) and high PSRR (82 dB at 1 kHz). It features thermal-overload and short-circuit protection, along with an enable control feature. The device is stable with 1-µF ceramic input and output capacitors and does not require a separate noise bypass capacitor.
Packaged in a compact 4-X2SON (1x1) with an exposed pad, the LP590745QDQNRQ1 is suitable for surface mount applications. It operates across a wide temperature range of -40°C to 125°C (TJ) and is AEC-Q100 qualified for automotive use.
Key electrical specifications include a low dropout voltage of 120mV typical at 250mA, a quiescent current of 12µA when enabled, and less than 1µA when disabled. The output voltage tolerance is ±2%.
