SG140A/SG140 SERIES
18V& 24V POSITIVE REGULATOR
ELECTRICAL CHARACTERISTICS (Note 1)
SG140 - 18
(Unless otherwise specified, these specifications apply over full operating ambient temperatures for SG140-18 with -55°C ≤ TA ≤ 150°C, and VIN = 27V,
IO = 500mA, CIN = 0. 33µF, COUT = 0.1µF and are applicable for the K, R, and IG - Power package - only. Low duty cycle pulse testing techniques are
used which maintains junction and case temperature equal to the ambient temperature.)
