... 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. ...

... ADJ 4.2 Output Current and Current Limiting The MCP1725 LDO is tested and ensured to supply a minimum of 0.5A of output current. The MCP1725 has no minimum output load, so the output load current can and the LDO will continue to regulate the output voltage to within tolerance. The MCP1725 also incorporates an output current limit. ...

... MCP1725 4.6 C Input DELAY The C input is used to provide the power-up delay DELAY timing for the power good output, as discussed in the previous section. By adding a capacitor from the C pin to ground, the PWRGD power-up time DELAY delay can be adjusted from 200 µs (no capacitance 300 ms (0.1 µF of capacitance on C DELAY See Section 1.0 “ ...

... Dropout voltage is defined as the input-to-output voltage differential at which the output voltage drops 2% below the nominal value that was measured with 0.6V differential applied. The MCP1725 LDO has R a very low dropout voltage specification of 210 mV (typical) at 0.5A of output current. See Section 1.0 “ ...

... V 2 IN(MAX) 10 µF I VIN The total power dissipated within the MCP1725 is the sum of the power dissipated in the LDO pass device and the P(I PWRGD construction, the typical I 120 µA. Operating at 3.465V results in a power dissipa- tion of 0.42 milli-Watts. For most applications, this is small compared to the LDO pass device power dissipation and can be neglected ...
