Note 1: IREG less than 50 mA, regulator on.
2: After IREG exceeds IREGmax, voltage regulator output will be reduced
until VREGoff is reached.

ICSP™ Considerations
The following should be considered when the MCP201
is connected to pins supporting in-circuit programming:
• Power used for programming the microcontroller
should be supplied from the programmer, not from
the MCP201
• The MCP201 should be left unpowered
• The voltage on VREG should not exceed the
maximum output voltage of VREG
• The TXD pin should not be brought high during
programming
