The LP2985-N is a micropower, low-noise, ultra-low-dropout voltage regulator designed to deliver up to 150mA of output current. It operates with an input voltage range of 2.5V to 16V and provides a fixed output voltage range of 1.2V to 5.0V for the new chip version, while the legacy chip supports 2.5V to 6.1V. The output accuracy is ¬±0.5% for the new chip and ¬±1% for the legacy chip, ensuring reliable performance across varying load and temperature conditions. This regulator features a low quiescent current of 71OºA at no load and 750OºA at full load, along with a shutdown current of only 1.12OºA for the new chip. It boasts a low output noise of 30OºV_RMS when paired with a 10nF bypass capacitor, and high power supply rejection ratio (PSRR) of 70dB at 1kHz and 40dB at 1MHz, making it suitable for noise-sensitive applications. The LP2985-N includes built-in protection features such as output current limiting and thermal protection, and is stable with a minimum output capacitance of 2.2¬µF. It is packaged in a compact 5-pin SOT-23 (DBV) package, making it suitable for space-constrained designs. Applications include mobile radios, cordless power tools, and motor drives, among others.
