TPS7A20: Need to confirm drop voltage for TPS7A20

Part Number: TPS7A20

Hi team,

I want  to use TPS7A2032PDBVR.   Need to confirm:

1. TPS7A2032PDBVR output voltage 3.2V?

2.  TPS7A2032PDBVR if it is 3.2v output voltage, I want to confirm when output current 60mA and TA max is 60C, the max drop output voltage. Because our input voltage is 3.3V. I cannot find in datasheet.

If  drop voltage for TPS7A2032PDBVR is higher than 100mv, pls recommend  to us a suitable part.

Our requirements:

1. Input 3.3v output 3.2V, output max current 60mA  TA:-40C~60C

2. max drop voltage<100mv when output current 60mA and TA 60C

2. SOT-23 or SOT-5

3. low noise and high PSRR, high output precision

4. can be adjust or fix output

5. use in instrument

Thanks very much!

Mickey

    Hey Mickey, 

    The output voltage of TPS7A2032PDBVR is 3.2V however, this device was not designed to operate with just 100mV headroom (Vin-Vout). 

    TP7A15 is designed to operate with small headroom but it does not have 3.2V fixed output.
