Unless otherwise noted, these specifications apply for the following test conditions |VI – VO| = 5 V and IO = 0.5 A. All characteristics are measured
with a 0.1-
μ
F capacitor across the input and a 1-
μ
F capacitor across the output. Pulse-testing techniques are used to maintain the junction
temperature as close to the ambient temperature as possible. Thermal effects must be taken into account separately.
Input regulation is expressed here as the percentage change in output voltage per 1-V change at the input.
