3.7 Regulated Output Voltage (V OUT )
The V OUT pin(s) is the regulated output voltage of the
LDO. A minimum output capacitance of 1.0 μF is
required for LDO stability. The MCP1725 is stable with
For adjustable applications, the output voltage is
connected to the ADJ input through a resistor divider
that sets the output voltage regulation value. This
ceramic, tantalum and aluminum-electrolytic
capacitors. See Section 4.3 “Output Capacitor” for
output capacitor selection guidance.
provides the user the capability to set the output
voltage to any value they desire within the 0.8V to 5.0V

range of the device.
3.6.2 Sense
For fixed output voltage versions of the device, the
SENSE input is used to provide output voltage
feedback to the internal circuitry of the MCP1725. The
SENSE pin typically improves load regulation by
allowing the device to compensate for voltage drops
due to packaging and circuit board layout.

The 2x3 DFN package has an exposed pad on the
bottom of the package. This pad should be soldered to
the Printed Circuit Board (PCB) to aid in the removal of
heat from the package during operation. The exposed
pad is at the ground potential of the LDO.
