STMicroelectronics 5-Channel Low Dropout Voltage Regulator, 500 mA Output Current, 6 V Output, DFN-8 Package LDLN050PU33R

STMicroelectronics LDLN050PU33R is a state-of-the-art 5-channel low dropout voltage regulator offering 500 mA output current with a fixed output voltage of 6 V and packaged in a compact DFN-8 surface mount package. It is engineered for industrial electronics, sensor modules, microcontrollers, and wireless IC applications requiring precise, low-noise power supply solutions.

This regulator employs a very low-resistance PMOS pass element that enables fast start-up times and improved power supply rejection (PSR). The device delivers stable and precise output voltage with excellent line regulation at 0.02 %/V and load regulation as low as 0.005 %/mA.

The LDLN050PU33R supports a wide input voltage range from 2.7 V to 6.5 V, making it flexible for various power designs. Operating temperature range extends from -40°C to 125°C, suitable for harsh industrial environments.

Its low quiescent current and noise-optimized design allow powering sensitive analog and digital circuits such as sensors, microcontrollers, and wireless communication modules with minimal signal interference.

The adjustable version of this regulator allows output voltage settings between 1.25 V and 6 V, while fixed voltage versions between 1.0 V and 4.3 V are available upon request. For fixed voltage models, an external capacitor can be connected to the CNR pin to minimize output voltage noise further.

The DFN-8 package ensures compact PCB footprint for modern electronic assemblies. Applications include industrial automation, instrumentation, communications equipment, and embedded systems where stable and noise-free power regulation is critical.
