mala ispravka, nije im potrebno ni deo od toga , low drop tipa su, tek 1,5 volti pri punom opterećenju.

7.4.2 Stability Consideration
Stability consideration primarily concerns the phase response of the feedback loop. In order for stable operation,
the loop must maintain negative feedback. The LM1085 requires a certain amount series resistance with
capacitive loads. This series resistance introduces a zero within the loop to increase phase margin and thus
increase stability. The equivalent series resistance (ESR) of solid tantalum or aluminum electrolytic capacitors is
used to provide the appropriate zero (approximately 500 kHz).
Aluminum electrolytics are less expensive than tantalums, but their ESR varies exponentially at cold
temperatures; therefore requiring close examination when choosing the desired transient response over
temperature. Tantalums are a convenient choice because their ESR varies less than 2:1 over temperature.
The recommended load/decoupling capacitance is a 10uF tantalum or a 50uF aluminum. These values will
assure stability for the majority of applications.
inače, temperatura od 60 stepeni je sasvim ok.
