TPS799: TPS79915 load transient response curve

Part Number: TPS799


my customer would like to use the TPS799 (TPS79915 variant) in their new project and would like to know what the load transient response is going to look like under the following conditions: Vin = 5V, Vout = 1.5V and load varies between 1 - 5mA. 

Some datasheets usually have a curve that describes this behaviour. but in this case the load transient response curve is not present in the datasheet. Could you please share this information if you have it internally.



  • Hi Stani,

    The transient response for the TPS79915 will be similar to that of the TPS799285 found in Figure 22 of the datasheet shown below. 

    This is a worst-case scenario with a large (1 mA to 150 mA) load step. In your customer's case the response will have less ringing since the step is only 4 mA, and LDOs are typically more stable with smaller load currents. This is why there is no ringing on the step-down (150 mA to 1 mA) transient response for the TPS799285.
