UNIT
† Pulse-testing techniques are used to maintain the virtual junction temperature as close to the ambient temperature as possible. Thermal effects
must be taken into account separately. All characteristics are measured with a 0.1-µF capacitor across the input and a 22-µF tantalum capacitor,
with equivalent series resistance of 1.5
Ω,
on the output.
‡ Dropout voltage is limited by the input voltage range, with minimum VI = 3.0 V.
