The LP2985-N is a low-noise, low-dropout voltage regulator capable of delivering up to 150 mA of output current. It operates with an input voltage range of 2.5V to 16V and provides a fixed output voltage of 5.0V with an accuracy of ¬±0.5%. The device features a low quiescent current of 71 ¬µA at no load and 750 ¬µA at full load, making it suitable for battery-powered applications. It has a shutdown current of 1.12 ¬µA in the new chip version, which helps conserve power when the regulator is not in use. The LP2985-N exhibits low output noise of 30 ¬µV RMS when using a 10 nF bypass capacitor, and it has a high power supply rejection ratio (PSRR) of 70 dB at 1 kHz and 40 dB at 1 MHz. It is designed to be stable with a minimum output capacitance of 2.2 ¬µF, which allows for flexibility in capacitor selection. The device includes protection features such as output current limiting and thermal shutdown, ensuring reliable operation across a wide temperature range of -40¬8C to +125¬8C. The LP2985-N is packaged in a compact 5-pin SOT-23 (DBV) package, making it suitable for space-constrained applications.
