The Texas Instruments LP2989AILD-3.3/NOPB is a precision low-dropout (LDO) linear voltage regulator designed for applications requiring a stable 3.3V output at up to 500mA continuous current. It features a wide input voltage range from 2.1V to 16V and an ultra-low dropout voltage, typically 310mV at 500mA load.
This regulator is optimized for use with ceramic output capacitors, enabling very low output noise, as low as 18µV typical with an external bypass capacitor. It includes essential protection features such as overcurrent, overtemperature, and short-circuit protection. The device also offers a shutdown mode that reduces quiescent current to less than 0.8µA and an error flag that indicates when the output voltage drops below nominal.
The LP2989AILD-3.3/NOPB is supplied in an 8-WSON (4x4) surface-mount package, suitable for space-constrained designs. Its operating temperature range is -40°C to 125°C, making it suitable for various environmental conditions.
