TLV62150: Input/Output Capacitor Selection

Part Number: TLV62150

Team,

I have a customer examining the TLV62150 for an upcoming design, and they want to know if it is ok to utilize any other type of capacitor apart from ceramic? From sections 9.2.2.2.2.1 and 2 of the datasheet, it looks like ceramic is chosen for the low ESR typically associated with these. If the customer takes ESR into account with their selection, is there any reason they could not use some other medium here?

    Hi Carolus,

    Ceramic caps provide the lowest impedance (ESR and ESL) which is critical for the proper operation of the device and lowest EMI. This device has not been tested with other cap types and they are not recommended.

    They can use smaller capacitance values in parallel to achieve the required total capacitance. Doing this can also allow a smaller case size cap to be used, which is generally more available at the present time.
