Product Specifications

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.

  • 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(PLP)1212-6 and SC-88A packages, both of which can utilize the space on board.

  • xx … Specify the set output voltage (VSET) within the range of −5.5 V to −1.0 V in 0.1 V steps.

* Auto-discharge function quickly lowers the output voltage to 0 V by releasing the electrical charge in the external capacitor when the chip enable signal is switched from the active mode to the standby mode.
