What is LD39200PU33R used for?

The LD39200PU33R is well suited for powering noise-sensitive analog and RF circuits that require clean 3.3V rails, such as PLLs, VCOs, and data converters. Its high PSRR and ultra-low dropout voltage make it a strong choice for battery-powered and post-DC/DC point-of-load regulation where efficiency and low headroom are critical. The integrated reverse current protection also supports multi-rail systems with sequencing requirements.

Frequently Asked Questions

How much dropout voltage does the LD39200PU33R introduce at full load?

The LD39200PU33R specifies a typical dropout voltage of 0.13V and a maximum of 0.25V while delivering up to 2A of output current, making it well suited for tightly regulated 3.3V rails with limited input headroom.

Which package and input voltage range should designers plan for when board space is limited?

The LD39200PU33R ships in a compact Small Outline No-lead package and operates from a 4.3V to 6V input supply, allowing dense placement on boards where both footprint and headroom above the 3.3V output are constrained.

Why do buyers check the factory lead time before specifying the LD39200PU33R?

STMicroelectronics lists a factory lead time of around 16 weeks and a YTEOL rating of 8 years for the LD39200PU33R, so procurement teams sourcing 2A LDO regulators for production programs should plan orders well in advance.
