  1. A single 220-µF tantalum capacitor is utilized.
  2. See the 5962R21203 SMD for additional information on the QML RHA devices and see the V62/23602 VID for additional information on the SEP RHA devices.
  3. The subgroups are only applicable for QML versions of the device; for subgroup definitions, see the Quality Conformance Inspection table.
  4. Additionally, VBIAS ≥ VIN and VBIAS ≥ VOUT + 1.6 V.
  5. PD is the internal power dissipation. When PD exceeds 4 W, the current is lowered to avoid excessive local heating (due to tester limitations).
  6. TID = 50krad(Si) for SEP parts.
