FCB, EXTVCC, PGOOD, RUN/SS, VOUT.......... –0.3V to 6V

VIN, SVIN, fADJ............................................ –0.3V to 20V

VOSET, COMP............................................. –0.3V to 2.7V

Operating Temperature Range (Note 2) ... –40°C to 85°C

Junction Temperature ........................................... 125°C

Storage Temperature Range................... –45°C to 125°C

(Note 1)

The ● denotes the speciﬁcations which apply over the –40°C to 85°C

temperature range, otherwise speciﬁcations are at TA = 25°C, VIN = 12V. External CIN = 120µF, COUT = 200µF/Ceramic per typical

application (front page) conﬁguration.
