Shutdown Input Timing

4.5 Dropout Voltage

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 a

VR + 1V differential applied. The MCP1811X/12X LDO

devices show a Low-Dropout voltage specification of

400 mV (typical) for all VR, and presents small varia-

tions in the dropout value with load and temperature

changes.

See Section 1.0 “Electrical Characteristics” for

maximum dropout voltage specifications.
