100V, 1A, synchronous step-down regulator: Iq of 7µA
https://www.electronics-lab.com/100v-1a-synchronous-step-down-regulator-iq-of-7%c2%b5a/
by Graham Prophet @ edn-europe.com: LT8631 is a 1A, 100V-input-capable synchronous step-down switching regulator. Synchronous rectification delivers efficiency as high as 90% while Burst Mode operation keeps quiescent current under 7µA in no-load standby conditions. Its 3V to 100V input voltage range suits it for 48V automotive systems, dual battery transportation, industrial and 36V to 72V […]

Use an LM317 as 0 to 3V adjustable regulator
https://www.electronics-lab.com/use-an-lm317-as-0-to-3v-adjustable-regulator-2/
by Vladimir Rentyuk @ edn.com: Most engineers know that they can use an inexpensive, three-terminal adjustable regulator, such as Fairchild Semiconductor’s LM317, as an adjustable regulator to only some necessary value of voltage, such as 36 or 3V. This value cannot be less than 1.25V without employing other approaches, however. The devices’ inner reference voltage is […]
