I want to build a circuit that generates current pulses of 50mA peak value .The pulse width is 15ms and occurs every 400ms. I found a reference circuit that produces pulses using 555 timer.

Ideally, I need the pulse peak value to settle within 99% of maximum, as shown in fig 2 in attached sketch.
How can this be achieved?
Can the existing circuit in above reference be improved further?
Is there any alternate method to produce current pulses that's very stable ?
Previously I have made voltage pulser, which was noisy. Then I connected a comparator to the voltage pulser output to obtain very clean and stable voltage pulses.
Thank you
