TPS60403: Any smaller package than the TPS60403 recommend

Part Number: TPS60403
Other Parts Discussed in Thread: LM27761


Customer is finding a Negative Voltage Regulator that need transfer the +2V to -2V.

Since the application is AR Glass, the package SOT-23 of TPS60403 is large for them. So do you have any recommend for this?



  • Hi William,

    There are very few inverters in the market, and this one can support your very low Vin.

    A smaller option is the LM27761, and this would need to run from a higher Vin such as the battery or a 3.3V rail.  The built-in LDO is probably desired to give a cleaner output voltage, but the efficiency will be lower.
