Part Number: TPS78233EVM-445 Other Parts Discussed in Thread: TPS7A02 , TPS7A03 , TPS7A05 , TPS780 , TPS781 Hi team,
We already used TPS78233DDCR for this part .but this is out of stock now. We need this part 10000 no's. Or else please suggest the alternate…
Other Parts Discussed in Thread: TPS780 Hello TI,
1. What is the TPS780 Ground pin current when in dropout? 2. What is the TPS780 Ground pin current when in Vout >= Vin (Vout & Vin down to 0V)?
Will the part stay well-behaved in this way or would…
Other Parts Discussed in Thread: TPS780 Hello,
what is the behaviour of the TPS780 when the Input Voltage is smaller than Vin_min = 2,2V.
Because for my application i would need a pass-trough function from the input to the output, starting with voltages…
Other Parts Discussed in Thread: TPS780 , TEST The TPS780 data sheet shows a typical value for Vfb of 1.216V for adjustable versions of the part, but no min/max values.
The Vout DC accuracy specification seems to apply only to the fixed output versions…
Hi TISL,
Unfortunately, the TLV761 has active pulldowns on both outputs. So if one is disabled it tries to pull down the rail.
We do have the TPS780 which has a pin selectable output but I only see a 3V/1.8V version released. We do not have a 2.8/1…
Hello Collin,
Attached you will find a screen shot from a working board. SDA is the yellow line and SCL the blue one.
From the non-working board we have not measurement, because there are no changes on the line.
In the meantime, we found out that on the…
Other Parts Discussed in Thread: TPS780 Hi,
I have a problem with parameters of TPS78001DDCR.
I gnd should be about 1 uA, but I have in some examples 70 uA (with vertical line).
This problem is only in exaples with vertical line on casing.
Is it a fake…
Other Parts Discussed in Thread: TPS780 , TEST Hello,
I am having some trouble with a TPS780 adjustable regulator. I am trying to regulate 5V down to 1.5V, but my constructed circuit is regulating it to 2.220V instead. I calculated that I should use a 1M…
Hi Rajesh,
The line regulation is a DC characteristic, the Vout vs. Vin is generated by a very slow sweep of Vin. Your simulation is a transient response. Based on the timescale, the switching from 4.5V to 5.5V is fast.
Please check figure 46. from the…
