MIC2950/2951
Micrel
The MIC2950 is available as either an -05 or -06 version. The
-05 and -06 versions are guaranteed for junction temperatures
from –40°C to +125°C; the -05 version has a tighter output and
reference voltage specification range over temperature. The
MIC2951 is available as an -02 or -03 version.
The MIC2950 and MIC2951 have a tight initial tolerance
(0.5% typical), a very low output voltage temperature coefficient
which allows use as a low-power voltage reference, and
extremely good load and line regulation (0.04% typical). This
greatly reduces the error in the overall circuit, and is the result
of careful design techniques and process control.

Pin Function
Regulated Output
Sense (Input): Output-voltage sensing end of internal voltage divider for
fixed 5V operation. Not used in adjustable configuration.
Shutdown/Enable (Input): TTL compatible input. High = shutdown,
low or open = enable.
Ground
Error Flag (Output): Active low, open-collector output (low = error,
floating = normal).
3.3V/4.85/5V Tap: Output of internal voltage divider when the regulator is
configured for fixed operation. Not used in adjustable configuration.
Feedback (Input): 1.235V feedback from internal voltage divider’s TAP (for
fixed operation) or external resistor network (adjustable configuration).
