The LM7705MMX/NOPB from Texas Instruments is a switched capacitor voltage inverter designed to provide a low-noise, fixed negative voltage of -0.232V. This device is particularly useful for low-voltage amplifiers, enabling their output to swing to zero volts by supplying the amplifier's negative supply pin. It operates within a supply voltage range of 3V to 5.25V and can deliver a maximum output current of 26mA.
The regulator boasts high conversion efficiency of up to 98% and a low quiescent current of 78µA, making it suitable for power-sensitive applications. It features synchronous rectification and operates over an industrial temperature range of -40°C to 125°C.
The LM7705MMX/NOPB is available in an 8-pin VSSOP package, measuring 14.7 mm² (3mm x 4.9mm). Its surface-mount design facilitates integration into compact electronic systems. The device is designed to prevent amplifier output saturation voltage issues in single-supply systems, thereby reducing error accumulation in subsequent gain stages.
Key electrical characteristics include a regulated output voltage of -0.232V with a 5% tolerance and an output voltage ripple of 4mV PP. The turn-on time is approximately 500µs, and the shutdown current is a mere 20nA.
