Dear Sir,

normally we use 555 in monostable mode.
The RC constantly drain current to the ground, and 555 takes up 100 uA current constantly.

I just wonder if there is another more recent design which has smaller package, consume less current which gives a defined pulse width when a trigger is received

Thanks in advance.

Tony
 

What about the 74HC125 or something from the CD-4000
series? Not likely smaller (though maybe there is a Tiny
Logic version) but most likely lower power. Use more timing
resistor and smaller timing capacitor to minimize power.
