APPLICATION INFORMATION
shutting down the TPS6040x
If shutdown is necessary, use the circuit in Figure 32. The output resistance of the TPS6040x will typically be
15
plus two times the output resistance of the buffer.
Connecting multiple buffers in parallel can reduce the output resistance of the buffer driving the IN pin.

GaAs supply
A solution for a –2.7-V/3-mA GaAs bias supply is proposed in Figure 33. The input voltage of 3.3 V is first inverted
with a TPS60403 and stabilized using a TLV431 low-voltage shunt regulator. Resistor RP with capacitor CP is
used for filtering the output voltage.
