For the Basic 2-Terminal Current Source circuit shown in Figure 13. ISET is determined by the following formula: ISET = 67.7 mV/RSET (@ 25°C). Set current error is expressed as a percent deviation from this amount. ISET increases at 0.336%/°C @ Tj = 25°C (227 μV/°C). (3) ISET is directly proportional to absolute temperature (°K). ISET at any temperature can be calculated from: ISET = Io (T/To) where Io is ISET measured at To (°K).
