Description

The RP117 is a negative voltage LDO regulator that provides high ripple rejection and low output noise. Adding only one capacitor to each input and output pin can make a simple structure and high performance LDO regulator.

Key Benefits

  • Provides high ripple rejection rate and low output noise, which is ideal for noise-sensitive devices.
  • Requires only one capacitor for each input and output pin, and is available in small DFN(PL)1212-6 and SC-88A packages, both of which can utilize the space on board.
