The Texas Instruments LP2981-N is a fixed-output, low-dropout (LDO) voltage regulator designed for various applications requiring stable power.
This specific part, the LP2981IM5X-3.3/NOPB, provides a 3.3V output voltage with an output current capability of up to 100mA. It features an input voltage range up to 16V and a low quiescent current of 95 µA. The regulator includes protection features such as over current, over temperature, and short circuit protection, enhancing its reliability.
Designed for surface mount applications, it comes in a compact 5-pin SOT-23-5 package. The operating temperature range is -40°C to 125°C, making it suitable for a wide array of environmental conditions. The device also incorporates an Enable control feature for power management.
Key electrical characteristics include a typical voltage dropout of 0.37V at 100mA and a PSRR of 63dB at 1kHz. The regulator is stable with 2.2µF ceramic capacitors, facilitating compact circuit designs.
