# TIOL1113: TIOL1113 LDO

Part Number: TIOL1113

Hi team,

Could you please share the temp drift(temp coefficient) data, especially its histogram and std.dev for the integrated LDO of TIOL1113?

I would like to also confirm followings.

- over operating free-air temperature range = -40C - 125C?

- min/max of LDO output voltage is NOT including line regulation condition and load regulation condition.

Best regards,
Iwata Etsuji

• Hello Iwata-san,

Here are some summary tables of the TIOL1113 LDO output voltage across temperature and the Min, Mean, Max, and Std. Deviation values from the data set.

 Summary of 3.3 V LDO Output Voltage Across Temperature -40   (C) 25   (C) 125 (C) Drift (V) (Max - Min) Min (V) 3.2850 3.2920 3.3010 0.0070 Mean (V) 3.3417 3.3454 3.3531 0.0120 Max (V) 3.3770 3.3790 3.3900 0.0210 Std. Dev (V) 0.0225 0.0213 0.0215 0.0037

I have also combined all of the data into a single data set and provided a summary of all measured LDO output voltage just in case that was of any interest to you.

 Combined data from all 3 temperatures Min (V) 3.2850 Mean (V) 3.3467 Max (V) 3.3900 Std. Dev (V) 0.0223

I have also plotted the Histograms for the individual temperature splits, the drift and the Combined data set.

Here is the drift plotted as a histogram:

Regarding the other questions:

- over operating free-air temperature range = -40C - 125C?

Yes, the device was characterized across a free-air temperature range of -40C to 125C and the parameters in the datasheet reflect data collected in this range.

- min/max of LDO output voltage is NOT including line regulation condition and load regulation condition.

Yes, you are correct.  The Voltage Regulator Output Voltage is given for an unloaded LDO.  There is a separate Load Regulation parameter LREG that covers the output voltage deviation across a 100uA to 20mA load.  This is given as a maximum value of 1% for the range.

Let me know if you have any additional questions.

Regards,

Jonathan
