Product Description

The RP111L301D-TR is a low-dropout (LDO) voltage regulator designed for compact applications, housed in a SOT-23-5 package. It accepts an input voltage range of 2.0V to 6.0V and delivers a fixed 3.0V output with a maximum current of 300mA, ideal for low-power devices requiring stable power. This LDO operates efficiently with a dropout voltage of 160mV at 100mA, ensuring reliable performance in industrial automation, IoT modules, and portable electronics. Its SOT-23-5 package enables space-constrained PCB designs, while a wide temperature range (-40°C to +125°C) supports harsh environments. Key advantages include low noise, high accuracy (±2%), and thermal protection. However, it lacks adjustable output or communication interfaces, limiting configurability. The RP111L301D-TR does not integrate battery management, display, or sensing functions, focusing solely on efficient voltage regulation.
