The LDO LP2981 is designed for supply microcontrollers ?
Explain better my question.
The datasheet recommend the use of tantalum capacitors on voltage outputs (ESR>1ohm) and strictly excludes ceramic capacitors.
This means that isn’t possible to supply microcontrollers because for them is always recommended a 100nF decoupling ceramic capacitors (ESR<<1ohm) for Vdd.
Thus, ceramic capacitors in parallel with tantalum capacitors reduce the ESR enough to go below the minimum stable value for the LP2981-N and cause oscillations.
In other words LP2981 isn't able to supply microcontrollers .
It’s correct ?
