Performance guaranteed over the indicated operating temperature range by design and characterization production tested at Tj = Ta = 25 °C. Low duty cycle pulse techniques are used during testing to maintain the junction temperature as close to ambient as possible. 9. IOUT > 50 mA at VIN > 50 V 10. Not characterized at VOUTNOM < 3.3 V. 11. Respect to SOA 12. Guaranteed by design and characterization |
