High PSRR LDOs

STMicroelectronics High PSRR LDOs are conceived for noise-sensitive and RF applications. This STMicroelectronics series of high-performance LDO regulators features remarkable power supply rejection ratio characteristics (up to 92dB at 1kHz). The LDOs also feature ultra-low noise operation (as low as 6.3µVRMS). This results in cleaner and stable output voltages suitable for ultra-sensitive loads. The devices' advanced design guarantees fast and stable dynamic performance with low power consumption.
