voltage provided a series resistor is used as shown in Figure 7.
The maximum allowed voltage on the ENABLE pin without
the resistor is 10 V. Direct voltages greater than 10 V applied
to the pin without the series resistor may damage the device.
The system designer should note the turn−on threshold (typ
1.4 V) is on the ENABLE pin. The threshold will be higher

availability, size and temperature constraints. A tantalum or
aluminum electrolytic capacitor is best, since a film or
ceramic capacitor with almost zero ESR can cause
instability. The aluminum electrolytic capacitor is the least
expensive solution, but, if the circuit operates at low
temperatures (−25°C to −40°C), both the value and ESR of
the capacitor will vary considerably. The capacitor
