Operating Ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits. Note 2: Unless otherwise specified, tests are performed at Tj = 25˚C with pulse testing so that junction temperature does not change during test Note 3: Set current is the current flowing into the V+ pin. For the Basic 2-Terminal Current Source circuit shown on the first page of this data sheet. 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). www.national.com 2 |
