The LP3965EMP-ADJ-NS from National Semiconductor is a high-current adjustable LDO regulator capable of delivering up to 1.5A. With a low dropout of 0.55V at full load and a quiescent current of 9 mA, it provides efficient power conversion for portable and industrial applications. The SOT-223 package offers a compact solution for adjustable output voltages up to 5.1V.
- High Output Current: 1.5A capability supports power-hungry processors and FPGAs.
- Low Dropout Voltage: 0.55V at 1.5A maximizes efficiency by allowing operation with minimal headroom.
- Adjustable Output: Flexible voltage setting from 1.216V to 5.1V for diverse design requirements.
- Good PSRR: 60dB at 120Hz reduces mains-frequency ripple in audio and precision circuits.
High-Current Portable Devices
