LP3985 datasheet



The LP3985 is designed for portable and wireless applications with demanding performance and space requirements. Power supply rejection is better than 50 dB at low frequencies and starts to roll off at 1 kHz. High power supply rejection is maintained down to low input voltage levels common to battery operated circuits.
