The Texas Instruments LP2981AIM5-2.5/NOPB is a fixed-output, low-dropout (LDO) voltage regulator designed for applications requiring up to 100mA of load current. It supports an input voltage range from 2.5V to 16V and provides a stable 2.5V output.
Key electrical characteristics include a low quiescent current of 69µA at no load (new chip) and a shutdown current of less than 1µA (legacy chip). The regulator features output current limiting and thermal protection for enhanced reliability. Its high PSRR performance of 75dB at 1kHz and 45dB at 1MHz helps attenuate noise from upstream DC/DC converters.
Packaged in a compact 5-pin SOT-23-5 (DBV) surface-mount package, the LP2981AIM5-2.5/NOPB is suitable for space-constrained designs. It operates within an ambient temperature range of -40°C to 125°C. The device includes an Enable control feature for power management.
This LDO regulator is designed to meet the needs of low-voltage microcontrollers and processors, offering ±0.5% output voltage accuracy for the new chip version over load and temperature. It is stable with 2.2µF ceramic capacitors.
