TYPICAL PERFORMANCE CHARACTERISTICS
Note: Unless otherwise indicated, C
OUT = 4.7 uF Ceramic (X7R), CIN = 10.0 µF Ceramic (X7R), IOUT = 1 mA, Temperature = +25°C,
VIN = 6.0V, RPWRGD_PULLUP = 10 kΩ To VOUT, VSHDN = VIN, and device is MCP1790.
Note: Junction Temperature (TJ) is approximated by soaking the device under test to an ambient temperature equal to the desired
junction temperature. The test time is small enough such that the rise in Junction Temperature over the Ambient temperature is not
significant.
