(°K). ISET at any temperature can be calculated from: ISET = IO (T/TO) Note 3: Set current is the current flowing into the V+ pin. It is determined where IO is ISET measured at TO (°K). by the following formula: ISET = 67.7mV/RSET (at 25°C). Set current error Note 5: VMAX = 40V for LM134 and 30V for other grades. 3
