Voltage regulator for low side switch gate control

A fluidic die comprising:

• a substrate;
• a power node on the substrate;
• a ground node on the substrate;
• fluid actuators supported by the substrate and grouped into primitives, each fluid actuator of each primitive comprising a resistor having a first side and a second side;
• a high side switch transistor electrically connected between the first side of each resistor of each fluid actuator and to the power node;
• a level shifter on the substrate and connected to the power node to generate a switch drive voltage for a gate of the first transistor based upon first control signals;
• low side switch transistors, each of the low side switch transistors electrically connected between the second side of a respective resistor of each of the fluid actuators and the ground node;
• second level shifters, each of the second level shifters to generate a second switch drive voltage for controlling a gate of a respective one of the low side switch transistors using a regulated predetermined voltage and based upon second control signals;
• and
• a voltage regulator on the substrate to supply power at a regulated predetermined voltage to the second level shifters, the predetermined voltage being greater than a voltage of the second control signals and independent of a resistance of the ground node.
