Hi, I need to generate 5V, +/- 0.25V at about 10mA from a DC supply that
can range between 4.5 and 6.5 volts. Is anyone aware of a circuit for
this, switchmode preferred for efficiency reasons. TIA
He said 4.5V in and at least 4.75V out...Wouldn't that be called, adding a voltage regulator to the existing
device?
is MAX761 suited??Hi, I need to generate 5V, +/- 0.25V at about 10mA from a DC supply that

Perhaps you are right, although the data states 5V is within the range"Den" <Invalid@someemail.com> wrote in message

12Volts is a bit high for his needs
But perhaps an MAX619 with a suitable zener regulator on the input to
limit the input voltage to the device for a maximum of 3.6 Volts.

Perhaps you are right, although the data states 5V is within the range
(5V<-->16.5V) of the '761 when in the "adjustable" configuration.
