The LP3985ITLX-2.7/NOPB is a precision low dropout linear regulator from National Semiconductor, delivering a fixed 2.7V output with up to 150mA of current. Its exceptionally low dropout voltage of 0.1V at full load enables efficient operation from nearly discharged batteries. The device is housed in an ultra-compact 5-DSBGA (1.5x1.2) package, ideal for space-constrained portable electronics. With a quiescent current of 150 µA and PSRR of 50dB at 1kHz, it provides clean, stable power for sensitive analog and RF circuits.
- Ultra-Low Dropout: 0.1V at 150mA allows operation from nearly depleted batteries, extending runtime.
- Minimal Footprint: 5-DSBGA (1.5x1.2) package is among the smallest available for LDOs.
- Clean Output: 50dB PSRR at 1kHz reduces noise for sensitive RF and analog applications.
- Proven Reliability: National Semiconductor design ensures consistent performance.
