The Texas Instruments LP2985IM5-2.9 is a micropower, 150-mA, low-noise, ultra-low-dropout regulator designed for use with very low ESR output capacitors. It operates from an input voltage range of 2.5 V to 16 V and delivers a fixed 2.9V output.
This LDO regulator features an ultra-low dropout voltage of 300 mV at 150 mA, ensuring efficient power delivery. It has a quiescent current of less than 1 µA when shut down and 75 µA at a 1 mA load. The device offers high peak current capability and is stable with low-ESR output capacitors as low as 5 mΩ.
Protection features include overcurrent, overtemperature, and short-circuit protection. The LP2985IM5-2.9 is suitable for battery-powered applications such as cellular phones, PDAs, and portable audio devices. It is available in a SOT-23-5 surface-mount package.
Key electrical specifications include a 1% output voltage accuracy (A Grade) and a PSRR of 45 dB at 1 kHz. The operating temperature range is -40°C to 125°C.
