Introduction

L6706 is a low-dropout (LDO) voltage regulator specifically designed for applications requiring low-noise, high PSRR and low quiescent power consumption. It works in a wide input voltage range from 1.8V to 6V, providing a stable output current of up to 200mA.L6706 also integrates a power saving system that switches off the internal regulator when detecting an over-current condition or an over-temperature event.

Applications

The L6706 provides excellent features and flexibility for use in power and voltage regulation in portable and handheld devices. It can provide stable and low noise power to a wide range of applications, such as computing, communications, portable and automotive electronics. Due to its low quiescent power consumption, the L6706 is also suitable for applications requiring ultra-low power consumption.

Working Principle

The L6706 is a low-dropout (LDO) voltage regulator that operates in a fixed regulated output voltage range of 1.6V to 6V. The output voltage is set by an external voltage divider and can be easily adjusted for non-standard output voltages. The L6706 uses an internal PMOS transistor to regulate the output voltage. The internal PMOS transistor is continuously switched on and off to maintain the voltage at the output pins. The device also contains temperature compensator circuitry that adjusts the output voltage according to the ambient temperature. The overload/over-current protection is managed by internal current regulator that monitors the device’s output current. When the output current exceeds the maximum allowed, the device shuts down the regulator and the output goes to a high impedance state. The device can also be enabled/disabled by the EN pin, which can be used to switch off the regulator while still allowing the logic circuitry to remain powered.

Conclusion

To summarize, the L6706 is an ultra-low power LDO voltage regulator specifically designed for applications requiring low-noise, high PSRR, and low quiescent power consumption. It offers excellent features and flexibility to provide stable and low noise power to a wide range of applications. In addition, the L6706 offers protection against over-current and over-temperature conditions and can be easily enabled/disabled via the EN pin. The simple selection of external components makes it easy to design with, making the L6706 an ideal choice for low-power voltage regulation.
