VR is the nominal regulator output voltage. For example: VR = 1.2V, 1.5V, 1.8V, 2.5V, 2.8V, 3.0V, 3.3V, 4.0V, 5.0V. The
input voltage VIN = VR + 1.0V; IOUT = 100 µA.
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.
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.
Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its measured
value with a VR + 1V differential applied.
The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable junction
temperature and the thermal resistance from junction to air (i.e., TA, TJ, JA). Exceeding the maximum allowable power
dissipation will cause the device operating junction temperature to exceed the maximum 150°C rating. Sustained
junction temperatures above 150°C can impact the device reliability.
The junction temperature is approximated by soaking the device under test at an ambient temperature equal to the
desired Junction temperature. The test time is small enough such that the rise in the Junction temperature over the
ambient temperature is not significant.  2005-2016 Microchip Technology Inc. DS20001826D-page 3
