Sub- Symbol Parameter Conditions Notes Typical(1) Min Max Units groups CLOAD Load Capacitor Stable Over Temperature See(3) 60 0 100 µF VHYST Thermal Hysteresis ΔT = -55°C to 125°C See(4) 20 ppm (3) Capacitive load not required but improves SET stability. This parameter is ensured by design and/or characterization and is not tested in production. (4) Thermal hysteresis is defined as the change in voltage measured at +25°C after cycling to temperature -55°C and the 25°C measurement after cycling to temperature +125°C. Where: VHYST = Thermal hysteresis expressed in ppm VR = Nominal preset output voltage VR1 = VR before temperature fluctuation VR2 = VR after temperature fluctuation. Post Radiation @ 25°C (1) The initial Reverse Breakdown Voltage tolerance is ±0.1% @ 100 μA. Qualification is performed with a 1.5X overtest. See for TOTAL IONIZING DOSE details.

Operational Life Test Delta Parameters This table represents the drift seen from initial measurements post 1000hr Operational Life Burn-In. All units will remain within the electrical characteristics limits post 1000hr Operational Life Burn-In. Deltas required for QMLV product at Group B, Sub- Group 5.
