_5_to__5_V_at_220_mA_with_low_power_inverter

This circuit uses two transistors to buffer the LX output and produce 220-mA of output current. The 2N3904 is used invert the LX output and drive the power pnp. When using external transistor buffers as shown here, the output voltage is set by the external feedback-resistor network ( 180 and 510 kΩ).
