... The MIC39300/1 is fully protected with overcurrent limiting, thermal shutdown, reversed-battery protection, reversed- leakage protection, and reversed-lead insertion. The MIC39301 offers a TTL-logic compatible enable pin and an error flag that indicates under voltage and over current conditions. Offered in fixed voltages, the MIC39300/1 comes in the TO-220 and TO-263 packages and is an ideal upgrade to older, NPN-based linear voltage regulators ...

... When the error flag is not used best to leave it open. The flag pin can be tied directly to pin 4, the output pin. Enable Input The MIC39301 version features an enable input for on/off control of the device. Its shutdown state draws “zero” current (only microamperes of leakage). The enable input is TTL/ CMOS compatible for simple logic interface, but can be connected 20V ...
