The STMicroelectronics LD39100PU18RY is a linear low-noise voltage regulator designed for power management applications. It provides a stable 1.8V output voltage with a maximum output current of 1A. The device features a low quiescent current of 200 µA, making it suitable for power-sensitive designs.
Key electrical specifications include a wide input voltage range from 1.5V to 5.5V, a dropout voltage of 200mV, and a maximum dropout voltage of 400mV at 1A. It offers good power supply ripple rejection (PSRR) of 62 dB at 1kHz and 65 dB at 10kHz. The voltage regulation accuracy is 2%, with line regulation at 0.01%/V and load regulation at 0.002%/mA.
This regulator is qualified to AEC-Q100 standards, indicating its suitability for automotive and demanding applications. It operates within a temperature range of -40°C to +125°C. The device is available in a compact 6-DFN (3x3) surface-mount package, facilitating integration into space-constrained PCBs.
Control features include Enable and Power Good signals, and protection features such as Over Current, Over Temperature, and Short Circuit protection are integrated for enhanced reliability.
