TPS7A49: Power supply for handheld luminometer

Part Number: TPS7A49
Other Parts Discussed in Thread: IVC102, LM27762, , TPS7A30, TPS7A94

Hi Team,

This inquiry is related to the other thread below. Our customer is looking for a low noise power supply for IVC102 precision transimpedance amplifier for a handheld luminometer. The LM27762 positive and negative output regulator is currently out of stocks. Are the TPS7A49 and TPS7A30 suitable for this application? If not, can you please suggest a suitable one?



  • Danilo,

    I think TPS7A30 is the best bet for the negative LDO. We don't have a huge negative LDO portfolio, unfortunately, so the options are limited.

    TPS7A94 is for sure the best for the positive LDO. It is expensive but has very low noise.
