STMicroelectronics Voltage Regulator 5.5V TSOT-23 5-Pin LDLN030G33R

STMicroelectronics LDLN030G33R is a high-performance voltage regulator designed to operate with input voltages ranging from 1.6 V to a maximum of 5.5 V. Encased in a compact TSOT-23 5-pin surface mount package, it is optimized for space-constrained power management applications.

This regulator features an ultra-low output noise specification of 7.5 μVRMS, making it highly suitable for sensitive electronic circuits requiring clean power supply. It delivers output currents up to 300 mA with exceptionally low dropout voltages of 100 mV at 200 mA and 150 mV at 300 mA, ensuring stable voltage regulation in low voltage differential conditions.

Power efficiency is enhanced by a very low quiescent current of 16 μA at no-load, and the device includes a controlled quiescent current during dropout, thereby optimizing energy consumption in battery-powered applications. The voltage output accuracy is maintained within ±2% tolerance across line, load, and temperature variations, contributing to robust circuit performance.

Additional safety features include undervoltage lockout, logic-controlled electronic shutdown, power good output signal, output discharge, internal soft-start to limit in-rush current, and comprehensive overcurrent and thermal protections.

Temperature operation ranges from -40 °C up to 125 °C, making it suitable for demanding industrial and automotive environments. The TSOT-23-5L package ensures seamless surface mount PCB integration, minimizing footprint and maximizing circuit density.
