6 FAQs about [How much is the transient output current of the battery]

Do batteries have a max current drain?

So, yes. Batteries have a max current drain (given by design and physical/chemical limitations) and yes the storage rating (being Ah, Wh or Joules) changes depending on battery design and load applied, and yes Wh is a better way to compare batteries because it takes voltage in account.

Does an output capacitor (Cout) improve load transient response?

Adding an output capacitor (COUT) is very effective in preventing this situation and thus improving load transient response. The next section describes the effect of an output capacitor (COUT) on improving load transient response. Load Transient Response of LDO and Methods to Improve it Application Note

What is load transient response?

The ability of an LDO to maintain a regulated output voltage in response to sudden changes in load current is called load transient response. Nowadays, there is a stringent requirement for load transient response. It is one of the most important parameters for LDOs.

What happens if load current is lower than load transient response?

In the following figure, the load current steps from 1 mA to 500 mA and then back to 1 mA in roughly 1 μ s. If the current change is lower or slower, the output voltage variation becomes lower than the load transient response shown below.

What are battery line transients?

The battery line transients are described in ISO 21780:2020 for 48 V systems and in ISO 7637-2:2011, ISO 16750-2:2012 §4.6.4 for 12 V/24 V battery systems. These specifications apply to road vehicles. Losses in RBP applications are predominantly due to conduction losses. i.e. current flow through the MOSFET channel on resistance, R DSon.

Why is a battery a constant voltage source?

A battery is a constant voltage source, and that´s what it´s going to do: provide a constant voltage to the circuit, regardless of current. your battery never determine the amount of current throw to the load, rather the load resistance and operating voltage of the load determine the amount of current.
