Part Number: TPS74801 Hi TI's technical engineer
We apply TPS74801 to design the power supply of the product, and test the output short, the steps are follows:
Case 1 Vout : 1.2V
Case 2 Vout : 1.8V
1st : output short
2nd : supply input 3.3V
3rd …
Part Number: TPS74801 Hi,
In our situation, the input is 3.3V and the output voltage is 2.8V, are there pin-to-pin compatible chips to replace TPS74801?
Thanks.
Part Number: TPS74801 Hi Team,
The customer reported that when there is a 1.4V voltage on the output side before the TPS74801 is powered on, the output voltage will not be accurate. The design Vout is 1.8V, Vout is 1.89V when abnormal, and Vfb is 0.86…

Part Number - TPS74801RGWR
In the data sheet of TPS74801RGWR , the land pattern recommendation has preferred Non- solder mask expansion over the solder mask expansion for the pins. Is there any specific reason for preferring Non-solder…

Dear All,
Is there a SIMPLIS model for TPS74801? How is the impedance(1.36mΩ) calculated here?
thx~

Part Number: TPS74801 Hi,
Customer raised question below.
Why that light load (<50mA) load regulation is poor?
TPS7173 datasheet shows this light load regulation is +1% which is almost occupied the entire DC load regulation window spec. regardless…
Part Number: TPS74801 Hello team,
In following schematic, the input is of 1.1V (Output of DC-DC) and the expected output is 0.925V. We have made 3 PCB for the schematic below, out of which 1 is working fine, and output voltage is 0.925V as expected.
Whereas…
Part Number: TPS74801 Hi ti,
Are these any internal pull up current source or pull low resister to the EN pin of TPS74801?
In order to disable the LDO's output before VIN has ramped, I try to drive EN from VIN by the typical RC-delay circuit.
VBIAS…
