Part Number: REF3033 Hello,
Our customer trying to use REF3033 and it connects to resistive load looks like attached.
They want to know the recommended capacitance for Cin and Cout, please let us know.
Thanks and best regards,

Other Parts Discussed in Thread: REF3033 , REF3030 Hi all,
I would like to know initial accuracy in Load condition and drop voltage when load current flow more than 25mA .
Please refer to the following specification.
Input voltage: 3.1~3.2V
load current…
Part Number: LM4041C Other Parts Discussed in Thread: REF4132 , LM4040 , REF3033 Greetings. We use the LM4041CEM3-ADJ component to create a ~3.3V reference. The feedback resistors are 10K and 16.9K, 1% tolerance, 100ppm. The shunt bias resistor is 140Ω from…

Hi team,
Could you share below information? We are considering whether REF3030 can be used in the system. One big concern is the dropout voltage. In order to estimate the…
Devin,
Some more info about "Vref is higher than Vdda". The Vref is fixed with 3.3V, from our Ref3033. Vdda comes from LDO (like 1117). 5V inputs and 3.3V outputs. But, actually it's a little less than 3.3V, like 3.27V. So Vref (3.3V) is higher than Vdda…
Hi Marcoo,
thanks for your answer!
Initial accuracy is not so much an issue, but temp co is. 60ppm/°C maximum for the REF3033 is a bit high. So I want to check the REF3133 and REF1933 too.
In the following plot you can see the behaviour of REF3133…
Hello Genovevo
REF3033 to power the microcontroller is not a correct method. It has a maximum output current of 25mA which would be way less than what is required to power up the microcontroller due to inrush current at power up!!!! If you connect a…
Hello Cynthia-san,
Our customers supply VA/VREF from REF3033.
As for when VA=3.3V,
how many volts should VREF be set to achieve the best electric characteristics?
I think that VREF have to lower the voltage slightly from VA.
Best regards,
Kato
