Texas Instruments LP2985-N Micropower 150 mA Low-Noise Ultra Low-Dropout Regulator in SOT-23 and micro SMD Packages LP2985AITPX-5.0/NOPB

The LP2985-N is a micropower low-noise ultra-low-dropout (LDO) 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 range of 1.2V to 5.0V, with an output accuracy of ¬±0.5%. The device features a low quiescent current of 71 OºA at no load and 750 OºA at full load, along with a shutdown current of approximately 1.12 OºA. This regulator exhibits low output noise of 30 OºV 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, making it suitable for applications requiring minimal noise interference. The LP2985-N includes built-in protection features such as output current limiting and thermal protection, ensuring reliable operation. It is designed to be stable with a minimum output capacitance of 2.2 ¬µF, and it comes in a compact 5-pin SOT-23 package, measuring 2.9 mm x 2.8 mm. Applications for the LP2985-N include use in washers, land mobile radios, active antenna systems, cordless power tools, and motor drives.
