Low-duty-cycle LED flasher/indicator keeps power draw at 4 mW

Battery-operated equipment often will benefit from a power-on indicator.   The indicator, however, can waste significant power. In situations where a low-duty-cycle blinking indicator provides an adequate indication of the power being turned on, the simple circuit described here should prove useful. Figure 1 Q1 and Q2 function as a current source and push a …
