LDLN030G33R Description

Short technical summary and product information.

The STMicroelectronics LDLN030G33R is a linear low-dropout (LDO) voltage regulator designed for applications requiring ultra-low noise performance. It features a fixed output voltage of 3.3V and can supply up to 300mA of current. The device includes Power Good and Soft Start functionalities, which are crucial for power sequencing in complex systems.

 

Key electrical characteristics include an input voltage range of 1.6V to 5.5V, a low quiescent current of 240 µA, and a dropout voltage of 150 mV at 300 mA. The regulator also offers excellent power supply rejection ratio (PSRR) and line/load regulation.

 

Designed for surface mount applications, the LDLN030G33R is housed in a compact TSOT-23-5 package. Its operating temperature range is -40°C to 125°C, making it suitable for a wide variety of environmental conditions. The device also incorporates over-current and over-temperature protection features for enhanced reliability.
