power supply

Therefore, you don''t need to have a regulator with "power good" detection or an additional supply monitor circuit in your specific case. Note that, if the MCU didn''t have the brown-out detection included, there are tiny chips that just offer this feature (often combined with a timed power-on reset generator) without being voltage regulators.

Power Considerations

regulation is a requirement. A battery power source is generally low in noise but will decline in voltage level as it discharges. The designer must take this into account as a design consideration.
