Sub FEP Drains
Sub FEP Drains

•Voltage regulators and DC/DC converters can place significant drains on batteries when operated outside their normal parameters when batteries will no longer operate a device

•The “off-state” drains can jump from micro-amps to milliamps when a LDO (low drop out) linear regulator drops out or DC/DC stops switching.

•Include a FET (field effect transistor) as a means of controlling the battery drain.

•If complete removal of load from the battery source is not possible, Energizer allows a maximum discharge current of 35 micro-amps.
