2.1.7 J7 – BIAS

Bias voltage standard banana connector.

If the input supply (VIN) voltage is less than 1.4 V but greater than 1.1 V, use a bias voltage of 3.0 V to 6.5 V to provide power to the TPS7A5301RPS (or TPS7A5301BRPS). If the input voltage is greater than 1.4 V, the BIAS pin does not have to be connected. The BIAS supply pin typically consumes 2.3 mA.
