LT3042 is designed and manufactured well. We haven't met any failure issue so far.
Dear All:
The LT3042 datasheet Table 1. is VOUT Voltage setting table ,this table show VOUT (V) 15V,12V,5V,3.3V,2.5V but I need 1.8V, 1.5V, 1.2V, 1.0V RSET resistors is how much?
Best Regards,
Jacky
The LT3042 is a 200mA part and that limits the above circuit to a maximum of 200mA output current. You can use the 500mA LT3045 instead of the LT3042, and that will increase the output current capability of the circuit. There is no LT3045 LTspice model at…
The datasheet only specifies the power supply ripple rejection for 120Hz.
Is there data at higher frequencies (100kHz to 1MHz)?
Is the performance close to chips such as LT3042?
What is the maximum current allow through the open collector PG pin? Nothing is stated in the datasheet. It looks like 100uA has been used for curves and examples.
Hello,
I am using the LT3042 for an ultra-clean 5V supply. In working to get the best performance I have followed the Appnote for the Demo Board, DC2246B regarding the Split Cap design.
My question is whether Pad 1 which connects to the GND Side of…
You're correct. When the part hits the current limit, the output voltage will drop for resistive loads.
ILIM cannot be used to as a current monitor. The internal circuitry is different from LT3042.
By shorting the inputs, you essentially eliminate the reference noise contribution from the measurements.
That being said, the switching regulator may be your problem. Have you tried disabling the regulator and powering the converter from a low noise bench…
