AP7375Q-50WR-7 ULDO Linear Regulator
The AP7375Q-50WR-7 is an automotive-qualified, ultra-low quiescent current (ULDO) linear regulator from Diodes Incorporated, delivering a fixed 5.0V output at up to 300mA continuous current and housed in a compact SOT-25 package for space-constrained automotive and industrial systems. Supporting a wide input voltage range of 3V to 45V, it features an ultra-low dropout voltage of 35mV at 10mA and 350mV at 100mA, plus a typical quiescent current of only 2.1μA, making it ideal for battery-powered and always-on applications.
Feartures and Applications
It provides a fixed 5.0V output with ±2% accuracy, supporting 3V–45V input and 300mA maximum load current for versatile power conversion. The ultra-low 2.1μA quiescent current and 35mV dropout at light loads optimize efficiency for low-power operation, while 85dB PSRR at 1kHz and excellent line/load regulation ensure clean, stable output voltage. It includes an active-high enable pin for remote on/off control, plus integrated short-circuit and thermal shutdown protection to safeguard the device and system during fault conditions. The SOT-25 package offers compact size and good thermal performance, being lead-free, RoHS-compliant, and halogen-free for environmental compliance.
This regulator is widely used in automotive electronics for powering ECUs, sensors, infotainment systems, and body control modules, leveraging its AEC-Q100 qualification and wide input range to handle automotive battery voltage fluctuations. It serves industrial automation for PLCs, instrumentation, and IoT edge devices, providing stable 5V power for microcontrollers, logic circuits, and low-power sensors. It is applied in consumer electronics for portable devices, smart home appliances, and battery-powered systems, benefiting from its ultra-low quiescent current and high efficiency. Additionally, it is utilized in medical devices and telecom equipment, delivering reliable, low-noise power in space-constrained and noise-sensitive designs.
