FIGURE 1-12: Voltage Regulator Output on Overcurrent Situation.
1.7 ICSP™ Considerations
The following should be considered when the
MCP2021/2/1P/2P is connected to pins supporting
in-circuit programming:
• Power used for programming the microcontroller
can be supplied from the programmer or from the
MCP2021/2/1P/2P.
• The voltage on V
REG should not exceed the
maximum output voltage of V
REG.
Note 1: I
REG less than 50 mA, regulator on.
2: After I
REG exceeds IREGmax, voltage regulator output will be reduced until VREG off is reached.
