The LP3990MFX-2.5 is a high-quality, high-performance LDO regulator from Texas Instruments, a leader in the semiconductor industry. This device is designed to provide a stable 2.5V power supply, ideal for noise-sensitive applications like RF and analog circuits.

• Current Capacity: 300mA
• Low Dropout Voltage: Ensures efficient operation even when the input voltage is very close to the output voltage.
• Low Noise Operation: With a noise level of 30µVRMS (10nF bypass capacitor).
• Power Supply Rejection Ratio (PSRR): 65dB at 1kHz, effectively suppressing noise and disturbances in the power supply.
• Package: Compact, 5-pin SOT-23
• Shutdown Mode: Reduces current consumption to less than 1µA when not in use, extending battery life.
