MIC39500/39501
with an input as low as 3.0V or 2.5V respectively. This gives
PNP-based regulators a distinct advantage over older, NPN-
based linear regulators.
A typical NPN regulator does not have the headroom to do
this conversion.
Minimum Load Current
The MIC39500/1 regulator is speci? ed between ? nite loads.
If the output current is too small, leakage currents dominate
and the output voltage rises. A 10mA minimum load current
is necessary for proper regulation.

Error Flag
The MIC39501 version features an error ? ag circuit which
monitors the output voltage and signals an error condition
when the voltage 5% below the nominal output voltage. The
error ? ag is an open-collector output that can sink 10mA
during a fault condition.
Low output voltage can be caused by a number of problems,
including an overcurrent fault (device in current limit) or low
input voltage. The ? ag is inoperative during overtemperature
shutdown.
When the error ? ag is not used, it is best to leave it open.
The ? ag pin can be tied directly to pin 4, the output pin.
Enable Input
The MIC39501 version features an enable input for on/off
control of the device. Its shutdown state draws “zero” cur-
rent (only microamperes of leakage). The enable input is
TTL/CMOS compatible for simple logic interface, but can be
connected to up to 20V.
