5.6 System Characteristics

The following specifications apply to a typical application circuit with nominal component values. Specifications in the typical

(TYP) column apply to TJ = 25℃ only. Specifications in the minimum (MIN) and maximum (MAX) columns apply to the

case of typical components over the temperature range of TJ = –40℃ to 125℃. These specifications are not specified by

production testing.

Deviation in VOUT from nominal output voltage value at VIN = 3.6V, VOUT = 5.0V, IOUT = 1mA to 1A. The max value is calculated by

(VOUT_MAX - VOUT_SET) / VOUT_SET * 100%, the min value is calculated by (VOUT_MIN - VOUT_SET) / VOUT_SET * 100%.
