ELECTRICAL CHARACTERISTICS The l denotes the specifications which apply over the full operating

temperature range, otherwise specifications are at TA = 25°C. VIN = VOUT(NOMINAL) + 0.2V, IOUT = 0mA, FB = OUT for the LTC1258 unless

otherwise noted.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings

may cause permanent damage to the device. Exposure to any Absolute

Maximum Rating condition for extended periods may affect device

reliability and lifetime.

Note 2: The LTC1258 is guaranteed functional over the operating

temperature range of –40°C to 100°C.

Note 3: If the part is stored outside of the specified operating temperature

range, the output may shift due to hysteresis.
