† Unless otherwise noted, these specifications apply for the following test conditions: VI − VO = 5 V and IO = 40 mA. Pulse-testing techniques must
be used that maintain the junction temperature as close to the ambient temperature as possible. All characteristics are measured with a 0.1-µF
capacitor across the input and a 1-µF capacitor across the output.
NOTE 3: Input voltage regulation is expressed here as the percentage change in output voltage per 1-V change at the input.
