Hi Matsunaga-san,
I tested a TPS73801 on the DEM-SOT223LDO and verified what your customer saw.
If Vin > 7.5 V, the output will not stay low even with En = 0 V.
With Vin = 12 V, Vout = 0.8 V with no load on the output.
With Vin = 12 V, I needed…
Part Number: TPS737 Other Parts Discussed in Thread: DEM-SOT223LDO , My customer is using TPS73701DCQR.
Customers designed with peripheral component constants described below.
Phenomenon①:There was a device whose output voltage dropped by about…
Hi Obinna,
This need is unique and we do not have a quick way to provide this type of output impedance model. The best way for the customer to make this evaluation is to obtain a DEM−SOT223LDO EVM board, populate a component and measure the output impedance…
Hi Sekiguchi-san,
The Vin ramp rate on the customer's board is in a middle region between fast ramp rate and slow ramp rate. In this middle region, some LDOs like the TPS737 will overshoot on startup. It is difficult to bound the amount of overshoot…
