The STMicroelectronics LD3985J33R is a fixed 3.3V positive linear voltage regulator IC designed for applications requiring stable power delivery. This component offers a 150mA output current capability with a low dropout voltage of 0.1V at 150mA, ensuring efficient operation even under moderate load conditions. Featuring an enable pin for control and protection against overcurrent and overtemperature, the LD3985J33R is suitable for demanding environments. Its low quiescent current of 150µA and a maximum input voltage of 6V, coupled with a compact 5-FlipChip (1.59x1.24) surface-mount package, make it an ideal choice for portable electronics, automotive systems, and industrial control applications. The device exhibits excellent power supply rejection ratios (PSRR) between 60dB and 50dB across the 1kHz to 10kHz frequency range. It is supplied in a Tape & Reel (TR) package for automated assembly.
