The LD39020TPU33R is a fixed output, positive linear voltage regulator from STMicroelectronics designed to deliver a stable 3.3V output at up to 200mA. It features a low quiescent current of 40 µA, making it suitable for battery-powered and low-power applications. The maximum dropout voltage is 0.35V at 200mA load, ensuring efficient operation even with small input-to-output voltage differentials.
This regulator includes built-in protection features such as over-current protection, over-temperature protection, and soft-start functionality. It also offers an enable control feature for power management. The device achieves a power supply rejection ratio (PSRR) of 80dB at 1kHz, decreasing to 55dB at 100kHz, providing good noise rejection for sensitive loads.
The LD39020TPU33R is housed in a compact 4-DFN (1x1) surface-mount package with an exposed pad for improved thermal performance. It operates over a junction temperature range of -40°C to 125°C, making it suitable for industrial and automotive environments. The input voltage range supports up to 5.5V.
