Overtemperature Protection

The MCP1726 LDO has temperature-sensing circuitry

to prevent the junction temperature from exceeding

approximately 150°C. If the LDO junction temperature

does reach 150°C, the LDO output will be turned off

until the junction temperature cools to approximately

140°C, at which point the LDO output will automatically

resume normal operation. If the internal power

dissipation continues to be excessive, the device will

again shut off. The junction temperature of the die is a

function of power dissipation, ambient temperature

and package thermal resistance. See Section 5.0

“Application Circuits/Issues” for more information

on LDO power dissipation and junction temperature.
