TPS7A05: TPS7A0530PDQNR GND CURRENT

Part Number: TPS7A05

Hi,

there are two questions regarding TPS7A0530PDQNR

1. Typical and maximum GND current at 100uA load

2.  Minimum input voltage needed to maintain 3.00V output at 50mA load 

 thanks!

 

Best Regards,

Patty Chuang

  • Hi Patty,

    The typical ground current for Iout=100uA will be Ignd=1.16uA. 

    The minimum input voltage for Vout=3V, Iout=50mA, and Tj=125C will be approximately Vin=3.067mV. Please note that the PSRR will not be very good with such low head room since the LDO will be right on the edge of regulation.
