The National Semiconductor LP2981AIM5.5.0 is a versatile low-dropout (LDO) voltage regulator designed for various power management applications. It can supply up to 100mA of output current with a maximum input voltage of 16V. The device features fixed output voltage options including 2.8V, 2.9V, 3V, 3.3V, and 5V, with an accuracy of ±0.5% for new chips.
Key electrical characteristics include a typical output noise of 160 µVrms and a high Power Supply Rejection Ratio (PSRR) of 75dB at 1kHz, making it suitable for noise-sensitive applications. The quiescent current is low, typically 69µA at no load for new chips. The regulator is designed to be stable with a minimum load capacitance of 2.2µF ceramic capacitors.
Packaged in a compact 5-pin SOT-23 (DBV) surface-mount package, the LP2981AIM5.5.0 is ideal for space-constrained designs. It operates reliably within an ambient temperature range of -40°C to 125°C, with an operating junction temperature range of -40°C to +125°C. The device includes output current limiting and thermal protection for enhanced reliability.
