The Bold specifications apply to the over full operating temperature range.
Note 1: Changes in output voltage due to heating effects are covered under the specification for thermal regulation.
Note 2: A 10µF output capacitor is required on CLM2830.
Note 3: Value shown for control circuitry (power transistor).
