Power Dissipation .. Internally Limited Storage Temperature Range ... –65°C to 150°C Input Voltage* .. 30V Lead Temperature (Soldering, 10 sec) .. 300°C Operating Input Voltage *Although the devices maximum operating voltage is limited, (20V for 3.3V, 3.6V Devices ... 20V a 3V, 5V device, and 25V for a 12V device) the devices are guaranteed 5V Devices ... 20V to withstand transient input voltages up to 30V. For input voltages 12V Devices ... 25V greater than the maximum operating input voltage some degradation of Operating Junction Temperature Range specifications will occur. For input/output voltage differentials greater than 15V, a minimum external load of 5mA is required to maintain regulation.
