Coefficient Note 1: The minimum VIN must meet two conditions: VIN and VIN VR + VDROPOUT(MAX). 2: VR is the nominal regulator output voltage when the input voltage VIN = VRated + VDROPOUT(MAX) or VIN = (whichever is greater); IOUT = 1 mA. 3: TCVOUT = (VOUT- high VOUT-LOW) *106/(VR * Temperature), VOUT- high = highest voltage measured over the temperature range. VOUT-LOW = lowest voltage measured over the temperature range.

8 4: Load regulation is measured at a constant junction temperature using low duty cycle pulse testing. Changes in output voltage due to heating effects are determined using thermal regulation specification TCVOUT. 5: Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below the output voltage value that was measured with an applied input voltage of VIN = VR + 1V or VIN = (whichever is greater). 6: The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable junction temperature and the thermal resistance from junction to air ( , TA, TJ, JA). Exceeding the maximum allowable power dissipation causes the device operating junction temperature to exceed the maximum 150 C rating. Sustained junction temperatures above +150 C can impact the device reliability. 7: The junction temperature is approximated by soaking the device under test at an ambient temperature equal to the desired junction temperature.

9 The test time is small enough such that the rise in the junction temperature over the ambient temperature is not significant. 2011-2013 Microchip Technology Inc. DS20002276C-page 5.
