Part Number: TPS7A94 Other Parts Discussed in Thread: TPS7A14 , TPS7A53B Hi, I have a board I'm working on that requires the following power rails:
19V @ 2A
5V @ 3A
3V3 @ 1A
1V05 @ 1A
I'm trying to figure out whether I should be using 4 discrete regulators…
Part Number: TPS7A94 The datasheet for the TPS7A94 reports that the fast charge up (here called soft-start) supplies extra current to ramp up the reference until the reference reaches 93% of the intended Vout value. However, there does not seem to be…
Part Number: TPS7A94 Other Parts Discussed in Thread: TPS7A96 Hi,
In data sheet to improve noise vs frequency performance at 1 MHz, it is suggested to use a Ferrite-bead Impedance = 49 @ 1MHz followed by a 1 uF capacitance. Can you please suggest some…
Part Number: TPS7A94 Other Parts Discussed in Thread: TPS7A96 As shown below,Can I use ferrite beads as ballast resistor as they have a given impedance value?
Thanks!
Hi James,
The FB_PG resistors need to be updated. Please set the bottom resistor (R1) to 12.4k and the top resistor (R2) to 221k and retest.
Thanks,
Stephen
Part Number: TPS7A94 Can you please say if the NR capacitor input is sensitive to noise and specifically one induced by voltage generated by the capacitor during vibration (due to its piezoelectric response if it is a ceramic capacitor)
For example,…
Part Number: TPS7A94 Hi team,
Could you review three schematics as below? Especially, could you review the input and output capacitors? There are concerns that capacitor value cosiderign DC-bias can't meet device recommendation.

Part Number: TPS7A94TPS7A94 - four instances of this low noise LDO in my design.
I'm coordinating design reviews through Peter James Miller
Please review my design. Schematic is shared with Peter.

Part Number: TPS7A94 Other Parts Discussed in Thread: LP3982 Hi dear people,
continuing with the supply for my design, I am now looking for the use of a TPS7A94 LDO.
My question is about the behaviour of the NR/SS pin.
I would need to implement the Dynamic…
Part Number: TPS7A94 Other Parts Discussed in Thread: TPS7A96 Hi,
On a current design, I would like to move from our simple LDO to the TPS7A94. We are concerned with noise, and the TPS7A94 appears to have excellent PSRR.
Our requirements for Vout include…
