Note 1:
Capacitor contribution (ESR component plus (1/f
OSC
)
·
C) is approximately 20% of output impedance.
Note 2:
All specifications from -40°C to +85°C are guaranteed by design, not production tested.
Note 3:
The MAX1719/MAX1720/MAX1721 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.
