SG140A/SG140 SERIES
12V POSITIVE REGULATOR
ELECTRICAL CHARACTERISTICS (Note 1)
SG140 A - 12
(Unless otherwise specified, these specifications apply over full operating ambient temperatures for SG140A -12 with -55°C ≤ TA ≤ 150°C, and VIN = 19V,
IO = 1.0A, 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.)
