† _{Pulse-testing techniques 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 10-µF capacitor with equivalent series
resistance within the guidelines shown in Figures 3 and 4 on the output. All measurements are taken with a tantalum electrolytic capacitor.
Although not normally recommended, an aluminum electrolytic capacitor can be used. Attention must be given its ESR value, particularly at low
temperatures.
