Part Number: TPS7A57 Hello,
What is the charge pump frequency?
If the charge pump is enabled (I don't want to disable it), what are your recommendations for reducing the noise?
Regards,
Fabien
Part Number: TPS7A57 Hi, Dear Product line engineer
one thing need double confirm associated with TPS7A57. as below figure shows, the internal charge-pump was disabled and internal circuit was powered by bias, right? under this conditions, could circuit…

Hi Experts,
The question is the Nominal input voltage suggested in the datasheet is Vin >= Vout + 0.4 V . In our customer's case, an output voltage of 1.2V so can we provide an input voltage of 1.4V and still get a proper output…
Part Number: TPS7A57 Its noted that only one resistor available at the REF pin which is connected between GND and REF pin.
We planned to control the REF pin using DAC for adjusting the O/P voltage. Noted the it doesn't have have the R1 resistor which…

Part Number: TPS7A57 We have used this LDO in our design and below is sch for for circuit implementation.
Initially this regulator o/p should be set it to 1.1V and then after 20mS it should set it to 2.5V.
To implement this, we have used the MOSFET…
Part Number: TPS7A57 Hi,
We are using TPS7A57 LDO for our design, we need to control this LDO by a sequencer. We would like to know whether the ENABLE pin in TPS7A57 is open drain/collector as we are not able to find this information in datasheet. …
Part Number: TPS7A57 I have an EMI application where I need to use a linear regulator to generate 0.85V from a 5V input. This load is 2A continuous but may go to 3.5A for 500ms at initialization. So for heat dissipation, I need to consider 2A@4.2V or…
Part Number: TPS7A57 Hi, in my application I am generating 5V out from a 5.4V input and would like to keep the charge pump disabled. I tied CP_EN low and connected VBIAS to the VIN input. Is this a valid configuration? I have tried simulating in LTSpice…
