Electrical Characteristics: Unless otherwise specified, all limits are established for V IN = V R + 1V, I LOAD = 100 μA, COUT = 1 μF (X7R), C IN = 1 μF (X7R), T A = +25°C. Boldface type applies for junction temperatures, T (Note 6) of -40°C to +125°C.

Note 1: The minimum V IN must meet two conditions: V IN 2.3V and V IN VR + 3.0% VDROPOUT .

• 2: VR is the nominal regulator output voltage. For example: V R = 1.2V, 1.5V, 1.8V, 2.5V, 2.8V, 2.9V, 3.0V, 3.3V, 4.0V, 5.0V. The input voltage V IN = V R + 1.0V; I OUT = 100 μA.
• 3: TCVOUT = (V OUT-HIGH - V OUT-LOW ) *10 6 / (V R * Temperature), V OUT-HIGH = highest voltage measured over the temperature range. V OUT-LOW = lowest voltage measured over the temperature range.
• 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 TCV OUT .
• 5: Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its measured value with a V R + 1V differential applied.
• 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 (i.e. T A , T J , 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.
• 7: 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.
• † Notice: Stresses above those listed under 'Maximum Ratings' may cause permanent damage to the device. This is a stress rating only, and functional operation of the device at those or any other conditions above those indicated in the operational listings of this specification is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability.

There is an internal electrical connection between the Exposed Thermal Pad (EP) and the GND pin; they must be connected to the same potential on the Printed Circuit Board (PCB).
