LDLN025M33R Description

Short technical summary and product information.

The STMicroelectronics LDLN025M33R is a high-performance linear voltage regulator designed for applications requiring a stable 3.3V output. It can deliver a continuous current of 250mA, making it suitable for a wide range of electronic devices.

 

This regulator features an ultra-low noise design and excellent power supply rejection ratio (PSRR) of 80dB to 60dB across a frequency range of 100Hz to 100KHz, ensuring clean power delivery. The input voltage range is specified from 4.3V to 5.5V, with a typical dropout voltage of only 0.2V at 250mA.

 

Protection features include over current, over temperature, short circuit, and soft start, enhancing reliability and system safety. The LDLN025M33R is housed in a compact SOT-23-5 package, suitable for surface mounting and space-constrained designs. Its operating temperature range is -40°C to 125°C (TJ).
