I have a system that is powered with 3 AA Alcaline batteries Varta Industrial Pro (1,5V@2950mAh).
The batteries are connected to a this 3V3 LDO that supplies power to a MCU. I have taken a minimum dropout of 150mV (so LDO would work down to 3V45). The MCU system will activate (using a FET) a electronic lock of this type, which consumes a maximum of 1000mA during 1 second and admits a voltage from 3V to 5V. As my LDO only supports up to 250mA I would like to know.
I would like to know if there would any problem connecting the lock directly to the three batteries power supply, as they are a not fixed voltage power supply.
In case there's no problem, would these three batteries in series be capable of maintaining the required voltage level when the lock is activated?
