6.3 Recommended Operating Conditions

–40°C ≤ TA ≤ 125°C (unless otherwise noted)
MIN NOM MAX UNIT
IQ Supply current (the device sinks additional current when VIN> VZENER(1)) 1 1.5 3 mA
VIN Voltage at the VIN pin(2)(3) (see Detailed Description) 6 V
VS Voltage directly from the supply before clamped by the Zener diode 6 330 V
CIN Input capacitor between VIN and GND(4) 1 4.7 µF
TA Operating ambient temperature –40 125 °C
(1) The device regulates the supply with an internal Zener diode. The device sinks up to 3 mA with the added supply current. See Equation 5 to find appropriate value for the RS resistor.
(2) The maximum input voltage of the device depends on the clamping voltage of the internal Zener diode, which changes over temperature. A current-limiting resistor is required to limit current to the Zener diode if the input voltage (VIN) is greater than VZENER. For more information on resistor sizing see the Detailed Description section and Application and Implementation section.
(3) For VS voltages less than VZENER, VIN = VS. For VS voltages greater than VZENER, VIN = VZENER.
(4) 4.7-µF input capacitor and full wave rectified 230-Vrms AC supply results in approximately 500-mV supply ripple.
