These specifications apply for 30V applied to the temperature may cause permanent damage to the device. Exposure to any Absolute stabilizer and –55°C ≤ TA ≤ 125°C for the LM199; and 0°C ≤ TA ≤ 70°C for Maximum Rating condition for extended periods may affect device the LM399. reliability and lifetime.
