Part Number: LM2937 Other Parts Discussed in Thread: LM317
Hello E2E,
Our customer is using LM2937 for mass product. An individual whose output voltage generates a voltage dip exists in the devices. Please see the attached file.
Voltage dip cycle and diping…
Part Number: LM2937-3.3 Hi team,
I am currently using LM2937ES-3.3/NOPB in one of my applications. In normal operation, this part will receive input from the 6V output of a flyback power supply.
One of the components powered by this 3.3V output is a CPLD…
Part Number: LM2937 Hello, All,
My customer find out extra symbols at top marking.
The first line is Lot#, it's clear.
2nd and 3rd lines is top marking according to datasheet. What does P+ at 3rd line mean?
Part Number: LM2937 Other Parts Discussed in Thread: LM317 Hello guys,
One of my customers asked me whether an external diode is needed from OUTPUT to INPUT for LM2937.
They found an external diode was connected from OUTPUT to INPUT on page 10 of LM317…
Part Number: LM2937 Hello,
A problem has happened to the output of LM2937 (the 5V output one). The schematic is shown below.
The TP106 is connected to a signal generator which outputs a pwm signal. The frequency and duty of the pwm signal could be adjusted…
Hi Chitharanjan, To use the internal RSET, you would need to keep the REXT bit of Control Register as 0. If you are using an external resistor, set the REXT bit to 1. For a SMT LDO for 24 V - 15 V, the LM2937 may be suitable. The 15 V version is the LM2937ESX…
Part Number: LM2937-3.3 I am using the LM2937ES-3.3 in my pcba. I get 5V all the way to the input pin when at output the regulator drops to 1.5V. If I lift the output leg and measure voltage I get about 4V. Is there a way to read the regulator off the…
