The LD3985M27R is a linear voltage regulator from Quarktwin Technology Ltd. designed to provide a stable output voltage of 2.7 V with an input voltage range of 2.5 V to 6 V. It can deliver up to 150 mA of output current, making it suitable for low power applications, particularly in battery-powered systems. The regulator features an ultra-low dropout voltage of 60 mV at a 150 mA load and a very low quiescent current of 85 ¬µA at no load, which helps prolong battery life. It is stable with low ESR ceramic capacitors and has a fast turn-on time of approximately 200 ¬µs. The device includes logic-controlled electronic shutdown to reduce power consumption when not in use. Additionally, it offers low noise performance with an output voltage noise of 30 ¬µV RMS over a frequency range of 10 Hz to 100 kHz and a power supply rejection ratio of 60 dB at 1 kHz. The operating temperature range is from -40 ¬8C to 125 ¬8C, making it suitable for a variety of environmental conditions.
