Unless otherwise specified, tests are performed at Tj = 25°C with pulse testing so that junction temperature does not change during test
(2)
Set current is the current flowing into the V+ pin. 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).
