... 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 ...

... Li-Ion cell batteries. 5.1 Input The input of the MCP1702 is connected to the source of the P-Channel PMOS pass transistor. As with all LDO circuits, a relatively low source impedance (10Ω) is needed to prevent the input impedance from causing the LDO to become unstable ...

... APPLICATION CIRCUITS AND ISSUES 6.1 Typical Application The MCP1702 is most commonly used as a voltage regulator. It’s low quiescent current and low dropout voltage makes it ideal for many battery-powered applications.

... P D(MAX) P D(MAX) 6.4 Voltage Reference The MCP1702 can be used not only as a regulator, but ) x 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 ...
