1. Characteristics and Specifications
NOTES:
1. (All Min/Max characteristics and specifications are guaranteed over the Specified Operating Condi-
tions. Typical performance characteristics and specifications are derived from measurements taken
at typical supply voltages and T_C = 25°C).

2. Long term operation at elevated temperature will result in reduced product life. De-rate internal power
dissipation to achieve high MTBF.
3. Output current rating may be limited by duty cycle, ambient temperature, and heat sinking. Under any
set of conditions, do not exceed the specified current rating or a junction temperature of 150°C.
