Is anyone using the Holtek HT75xx-1 series of LDO regulators?
They're available at aliexpress.com for a few US cents in small
quantities.
I bought a small batch last year and they work but I haven't got
around to testing them for things like ripple rejection, dropout
at different currents, etc. In case anyone is interested, here
are some of the features -
Vin max = 30V (old versions 26V)
Imax = 100mA
Iq = 2.5uA
Output range 2.1 to 12V (previously 3.3-5V)
Tolerance 3%
Vdo = 25/30mV at 1mA (old versions 100mV)
Package - various
Datasheet:
