Part Number: TPS7A47 Other Parts Discussed in Thread: TPS7A49 , TLV767 Hello experts,
I had some questions about Iq of TPS7A47 & TPS7A49,
As image below (apps note SLVA079), I see that Iq is proportional to output current. However, I couldn't find "Iq…
Part Number: TPS7A47 Hi team,
The power supply circuitry referred to the ADS1285EVM. That means I chose the TPS7A47 device as the power supply for my circuit.
On the left is my circuit, layout and output noise, on the right is the ADS1285EVM 's

Part Number: TPS7A47 I'm using this part to regulate from 7.5v to 7.0v at 600mA. Now I need the same for 1500mA. I have not been able to find any low noise (for RF) linear regulators that support 1.5A AND also Vin> 7v.
Can I parallel two of th…
Part Number: TPS7A47-Q1 Hi team,
When I add the input from 5V to 20V and the output is kept at 3.3V, is it normal for the device temperature to go from 30 degrees to nearly 100 degrees?
If the maximum input voltage of the device of 35V needs to be reached…
Part Number: TPS7A47-Q1 Other Parts Discussed in Thread: TPS7A47 Hi team,
I have some questions about LDO front-end capacitor selection. As mentioned in the user manual, the input voltage range of TPS7A47 is -0.4~36V， in Typical Application chapter, the…
Part Number: TPS7A47-Q1 Other Parts Discussed in Thread: TPS7A47 Hi,
When TPS7A47's output is short when VIN=36V, VOUT=1.4V and IOUT is short. Therefore the power dissipation on pass FET will be about 36*1.26=45W. Will thermal shutdown protects the device…
Part Number: TPS7A47 We're considering using an ANY-OUT LDO and an I2C IO Expander, such as outlined in appnote SBVA035A, to change the LDO output setting under firmware control. What's not clear to us is if this can be done on the fly, while the…
Part Number: TPS7A47-Q1
Hi Team,
My customer is using TPS7A47-Q1 and recently reports 5 failure cases (in total 30 boards).
Background:
1) Input voltage: 24.5~28V (Input comes from the multi-windings Flyback, it's the aux-winding output and varies due…
Part Number: TPS7A47 Hi team,
My customer is using LT3042 now.
And I wonder if we have a device to replace it, I saw TPS7A47(5mm*5mm), but it is bigger than LT3042 (3mm*3mm)
Requirements:
High PSRR
Enable pin
small size
Thanks,
Brian

Hello team, My customer has a question about noise performance vs Output Capacitor value. Would you please share the noise performance in case of Cout = 10uF case?
In ds, the following is described. 8.2.2.1.1 Input and Output Capacitor…
