Power supply IC generates low-noise bipolar (+/-) power rails
https://www.electronics-lab.com/power-supply-ic-generates-low-noise-bipolar-power-rails/
by Graham Prophet @ edn-europe.com: LTC3265 is a high voltage, highly integrated, low noise dual output power supply IC which takes a single positive input supply (VIN_P) and generates low noise bipolar rails up to ±2•VIN_P without any inductors. High voltage boost and inverting charge pumps deliver low noise dual outputs with post-regulating ±50 mA LDOs […]
