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.

Note

1:

The minimum VIN must meet two conditions: VIN  2.3V and VIN VR +2.5% VDROPOUT.

2:

VR is the nominal regulator output voltage for the fixed cases. VR = 1.2V, 1.8V, etc. VR is the desired set point output

voltage for the adjustable cases. VR =VADJ x((R1/R2) + 1). See Figure 4-1.

3:

TCVOUT =(VOUT-HIGH –VOUT-LOW)x 10

6/(VR x Temperature). VOUT-HIGH is the highest voltage measured over the

temperature range. VOUT-LOW is the lowest voltage measured over the temperature range.

4:

Load regulation is measured at a constant junction temperature using low duty-cycle pulse testing. Load regulation is

tested over a load range from 1 mA to the maximum specified output current.

5:

Dropout voltage is defined as the input-to-output voltage differential at which the output voltage drops 2% below its

nominal value that was measured with an input voltage of VIN =VR +0.5V.

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., 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 125°C can impact 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.
