ELECTRICAL CHARACTERISTICS
Unless otherwise specified, these specifications apply over the operating ambient temperature of 0°C to +125°C for LX8941CP; VIN = 10V, IO = 1A, COUT
= 22µF, and are for DC characteristics only. (Low duty cycle pulse testing techniques are used which maintains junction and case temperatures equal
to the ambient temperature.)
