The Texas Instruments LP2981AIM5-5.0 is a fixed-output, low-dropout (LDO) linear voltage regulator designed to provide a stable 5V output at up to 100mA.
This regulator supports an input voltage range from 2.5V to 16V for newer chip versions and 2.1V to 16V for legacy versions. It features a low quiescent current, with typical values of 69µA at no load for new chips. Protection features include over-current, over-temperature, and short-circuit protection, enhancing its reliability in various applications.
The LP2981AIM5-5.0 is available in a compact 5-pin SOT-23-5 (DBV) surface-mount package, making it suitable for space-constrained designs. It operates reliably within an ambient temperature range of -40°C to 125°C.
Key electrical specifications include an output voltage accuracy of ±0.5% for new chips and ±0.75% for A-grade legacy chips. The device also offers a Power Supply Rejection Ratio (PSRR) of 75dB at 1kHz for new chips, indicating good performance in rejecting input voltage ripple.
