current in applications where high capacitive loads are
used.
The MIC2033 is offered in both 6-pin SOT-23 and 6-pin
2 mm x 2 mm thin DFN packages. The MIC2033 has
an operating junction temperature range of –40°C to
+125°C.

† Notice:
Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.
This is a stress rating only and functional operation of the device at those or any other conditions above those indicated
in the operational sections of this specification is not intended. Exposure to maximum rating conditions for extended
periods may affect device reliability.
‡ Notice:
The device is not guaranteed to function outside its operating ratings.
Note 1:
Devices are ESD sensitive. Handling precautions are recommended. Human body model, 1.5 kΩ in series
with 100 pF.
