Part Number: TPS7A94 Hi, TI Engineers:
I'm now using the TPS7A94EVM to evaluate the performance of this chip and have noticed the following issues:
Here's my key circuit parameters:
Input Cap: 10uF *1pcs
Output Cap: 10uF *1pcs
R6 = 12k, C7 …
Part Number: TPS7A94 Hi Experts,
I am debugging an issue with the TPS7A94 LDO and would appreciate your advice.
According to the datasheet, the output voltage should be set by the NR/SS pin current and the external resistor:
VOUT = INR/SS × RNR…
Part Number: TPS7A94 Tool/software: Please review this schematic for the TPS7A94. It is one of six implementations of the LDO that I have in my design, with VOUTs of +0.75 V, +0.8 V, +0.9 V, +1.5 V (two instances) and +1.8 V.
For this schematic:
…
Part Number: TPS7A94 Tool/software: Hi,
Attached is the schematic. My requirement is to regulate 5.3 V down to 5 V. The datasheet specifies an input voltage range of 1.7 V to 5.7 V, but it does not provide a derating curve for input voltage.
Could…
Part Number: TPS7A94 Dear Team,
1)
we had a coment from your side on previus linked post:
"resistor divider network to FB_PG must still be populated. The device samples the parallel impedance at FB_PG during startup, which is used internally for…
Part Number: TPS7A94 Tool/software: I want to replace the LT3045 with the TPS7A94. The LT3045 also uses a resistor between the SET pin and GND to set the VOUT. A DAC output can also be connected to the LT3045 SET pin, so that DAC VOUT = LDO VOUT. I need…
Part Number: TPS7A94 Other Parts Discussed in Thread: TPS7A49 Dear Team,
we are designing TPS7A94 and have some questsions
Vin = 5V , Vout = 3.6V
1) We don't need PG function is it ok
-> Connect PG (pin 4) to GND ?
-> Use only 10k pull down…
Part Number: TPS7A94 Hi,
In the 1A PSpice transient model (SBVM988), I change the Css to 4.7uF, and run the simulation, the Vout ramp time goes to hunderds of ms, which is dramastically different from the value give in the DS. Where is wrong?
Thanks…
Part Number: TPS7A94 Other Parts Discussed in Thread: TPS7A96 , TPS7A33 Dear Team,
we would like to replace following LDO ( LT3045, LT1963, LT3015)
1) Please can you comment TPS7A94 as replacment for LT3045 (+5V out) in regards to output noise and…
Part Number: TPS7A94 Hi TI Support,
The TPS7A94 datasheet states that I_CL will be 100% if the parallel impedance of the R_FB network is less than 12.5k (sampled during startup).
I understand that picking 12.4k for the R_FB_PG(bottom) (as recommended…
