Note 7: Output resistance is guaranteed with capacitor ESR of 0.3Ω or less.

Note 8: All specifications from -40°C to +85°C are guaranteed by design, not production tested.

Note 9: The MAX1697 may draw high supply current during startup, up to the minimum operating supply voltage. To guarantee

proper startup, the input supply must be capable of delivering 90mA more than the maximum load current.
