is it real?
making it suitable for applications that mandate very low standby current. The TLV1117LV family of LDOs is also stable with 0 mA

#8473 Now:

- 1x18650 + charger +protection + SEPIC 5V -> 3.3V LDO regulator -> Atmega328 + ESP-07 -> 7 days counting data collection , burst mode, 1/s
- 2x18650 + SEPIC 5V -> 3.3V LDO regulator -> Atmega328 + ESP-07 -> 11 days and counting data collection , burst mode, 1/s

Next: 682250 Li/PO 700mA (48x22x7mm) + 2-5V boost converter + esp-12 with and without Atmega/STM32.

Funny enough, I don't see any power consumption over 120mA. Need some time to put together a proper test environment to generate some decent graphs.
