Overview of LDK120PU33R by STMicroelectronics
The LDK120PU33R is a fixed 3.3V, 200mA low dropout regulator (LDO) that stands out for its low quiescent current and very low noise output. Housed in a DFN-6 (Dual Flat No leads) package, this LDO features an impressively small footprint with dimensions of 1.3 x 1.2 mm and a maximum seated height of just 0.5 mm. It is engineered to operate within a wide input voltage range of 4.3V to 5.5V, accommodating various applications, and it manages to maintain performance with a nominal dropout voltage of 1V. Significantly, the LDK120PU33R boasts a robust operating temperature range from -40°C to 125°C, making it versatile for demanding environments.
With its low noise output and tight voltage tolerance (maximum of 3%), this LDO is particularly suitable for noise-sensitive applications where maintaining a clean and stable power supply is critical. It also complies with high industry standards, including RoHS, REACH, and is classified under ECCN code EAR99, indicating broad approval for export. As of the current time of writing, the factory lead time for this part is approximately 20 weeks, suggesting planning ahead for procurement is advisable.
