Part Number: LM27762 Other Parts Discussed in Thread: INA821 , REF3318 , , TPS7A39
Based on my device it needs to be low noise between 0.1-20Hz. My +-5v is mainly for the ina821 instrumentation amplifier, which has a PSRR of 120db.

Part Number: LM27762 Hi,
We're using an LM27762 on a new design to provide a negative bias rail of about -2.9V with a small current of around 2mA.
With the values shown in the schematic below I find that the negative rail gets into some sort of start…
Part Number: LM27762 Hello Experts,
My customer ask a question about output voltage range.
From datasheet, negative output voltage range is -1.5V to-5V, but is it okay to use -1.3V? There is no information about ratings
Best Regards,
Aust…
Part Number: LM27762 Hi sir/mam.,
I have used the LM27762 part in my design. But currently its out of stock so I want to know whether any footprint and pin compatible IC is available or not for the below component.

Part Number: LM27762 Hi team,
In the case that positive and negative output voltage supply at same time, the leak current between OUT+ to OUT- may affect for OUT- output.
I think this leak current path which can through biggest leak current is FB…
Part Number: LM27762 Other Parts Discussed in Thread: LM27761 Hi, we noticed the following issue with LM27762: the device disturbs our power supply line and its own outputs, it adds ripple in the kHz-range (e.g. at ~41kHz+mulitples). We have seen that…
Part Number: LM27762
im trying to obtain a +2.5V and -2.5V for the reference to an op-amp(Current draw is negligible). my Vin is 5V(Measured is 4.89) and when I measure my outputs I get -1.25 and 4.8V and the feedbacks are FB+ 0.741V, FB- -0.786V.
Part Number: LM27762 The data sheet of LM27762 explains that if you do not use the PGOOD function, connect it to the ground, but since the PGOOD terminal is an open drain, I think that you can open it without connecting it to the ground. I don't understand…
Part Number: LM27762 Hi team,
My customer is using our LM27762 for a light load (around 10mA , ripple concern circuit).
And, it seems that LM27762 will enter into PFM mode which is not good for signal chain load. Customer is asking whether there…
Part Number: LM27762 Hi TI
When Vin = 5V
1. Whether it can output continuously at ± 4.7V and 120mA?
2. Can the voltage drop be less than 200mV?
Is there any product that can cover this chip, but the low temperature can reach -55 ° recommended…
