... Figure 4-1). 4.2 Overcurrent The MCP1702 internal circuitry monitors the amount of current flowing through the P-Channel pass transistor. In the event of a short-circuit or excessive output current, the MCP1702 will turn off the P-Channel device for a short period, after which the LDO will attempt to restart ...

... P D(MAX) 6.4 Voltage Reference ) x The MCP1702 can be used not only as a regulator, but also as a low quiescent current voltage reference. In many microcontroller applications, the initial accuracy of the reference can be calibrated using production test equipment or by using a ratio measurement. When the initial accuracy is calibrated, the thermal stability and line regulation tolerance are the only errors introduced by the MCP1702 LDO ...

... For some applications, there are pulsed load current events that may exceed the specified 250 mA maximum specification of the MCP1702. The internal current limit of the MCP1702 will prevent high peak load demands from causing non-recoverable damage. The 250 mA rating is a maximum average continuous rating ...
