The fact that a switcher''s supply current draw increases with decreasing supply voltage may in some cases cause battery voltage to drop more "suddenly", but the effect won''t be overly large when using a buck converter for moderate step-down ratio, and it''s a result of drawing less current from a good battery than would a linear. $endgroup$

How to reduce DC voltage using resistors?
The short answer is "don''t do that." The voltage dropped by a resistor is given by Ohm''s Law: V = I R. So if you know exactly how much current your device will draw, you could choose a resistor to drop exactly 7.5 V, and leave 4.5 V for your device, when that current is run through it.

3.2: Rectification
To prevent excessive and possibly destructive current draw by the Zener diode, the voltage difference between the capacitor voltage and the Zener potential is dropped across a series current limiting resistor. This limiting resistor will set the maximum amount of output current. This current is then split between the Zener diode and the load.
Limiting current WITHOUT dropping voltage
Generally your current limiting circuit will require a bit of voltage "headroom" to operate in. That means you''ll need an unregulated PSU of > 5 V and regulate it down to 5 V while monitoring the current. …
