... The delay between regulated output level and fl ag indication is programmable with a single capacitor. The LT3011 also has the ability to operate with very small output capacitors stable with only 1μF on the output. Small ceramic capacitors can be used without the addition of any series resistance (ESR common with other regulators ...

... LT3011 APPLICATIONS INFORMATION in a small package, but they tend to have strong voltage and temperature coeffi cients, as shown in Figures 2 and 3. When used with a 5V regulator, a 16V 10μF Y5V capacitor can exhibit an effective value as low as 1μF to 2μF for the DC bias voltage applied and over the operating tempera- ture range ...

... For continuous normal conditions, the maximum junction temperature rating of 125°C (LT3011E/ LT3011I) or 150°C (LT3011H) must not be exceeded important to give careful consideration to all sources of thermal resistance from junction to ambient. Additional heat sources mounted nearby must also be considered ...

... Some tantalum capacitors are available for high temperature operation, but ESR is often several ohms; capacitor ESR above 3Ω is unsuitable for use with the LT3011. Ceramic capacitor manufacturers (Murata, AVX, TDK and Vishay Vitramon at this writing) now offer ceramic capacitors that are rated to 150° ...
