Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by characterization and are not production tested. 9. At maximum VIN of 26.5V, minimum VOUT is limited 28V. 10. Varies within range specified by VHEADROOM_RANGE. Electrical Specifications V IN = 12V, EN = 5V, RSET = 20.1kΩ, unless otherwise noted. Boldface limits apply across the operating temperature range, -40°C to +85°C. (Continued) PARAMETER SYMBOL CONDITION MIN (Note 8)TYP MAX (Note 8)UNIT |
