Pin Function
No connect. Not internally connected.
Soft start (Input). Connect a capacitor to GND to slowly turn on the device. The
higher the capacitance, the longer the turn-on time.
Feedback (Input): Output voltage sense node. Connect external resistors to set
the output voltage. Nominal feedback voltage is 1.245V.
Analog Ground
Power Ground
Switch Node: Internal power BIPOLAR collector.
Over-Voltage Protection (OVP): Connect to the output voltage to clamp the
maximum output voltage. A resistor divider from this pin to ground could be
used to raise the OVP level beyond 6V (max).
Supply (Input): 2.5V to 10V for internal circuitry.
Enable (Input): Applying 1.5V or greater enables the regulator. Applying a
voltage of 0.4V or less disables the MIC2253. Do not leave floating.
Compensation pin (Input): Add external R and C to GND to stabilize the
converter.
