Incorporating our latest »Green Operation« (GO) technology, the XC6705/06 sets a new benchmark for high performance linear regulators and allows designers to achieve »Seamless Operation« independent of IOUT value. As the output voltage is fixed during the production process (selectable in 100mV steps between 2.5V~5.5V), only two small 1.0μF ceramic caps are needed externally, as shown in Figure 1.   

By combining ultra-low quiescent current with high ripple rejection and fast transient response the XC6705/06 is a truly versatile linear regulator suitable for a wide range of applications.

Maximum operating voltage is 20V and maximum output current is 200mA. Drop-Out Voltage is 430mV (VOUT=5.0V@100mA) and this new LDO features both current limit, short circuit protection & thermal shutdown as standard features. Additionally, the XC6705 includes an optional CL discharge function and both the XC6705 & XC6706 feature soft-start to supress inrush current at start-up.

Seamless Green Operation

The GO (Green Operation) function of the XC6705/06 series enables a low quiescent current of 1.2μA with 50dB high power supply ripple rejection.

The supply current of the LDO will rise and fall as the output current demands changes. When the output load rises, the responsiveness of the internal error amplifier improves, which increases the LDO performance and as the output load decreases the responsiveness of the error amplifier reduces and supply current falls, as shown in Figure 2. As a result, both low current consumption at light load and high-speed response at heavy load are achieved.

High PSRR 

Our GO circuit automatically reduces quiescent current at low output loads down to only 1.2 µA, whilst offering extremely fast ripple rejection of 50 dB @ 1 kHz (Figure 3) 

Fast Load Transient Response

The XC6705/06 also provides fast load transient response performance ensuring that the output voltage remains stable as the load current changes as Figure 4 shows:

Typical Application (Industrial IoT Sensors)

By combining Low Power Consumption with High-Speed Operation using our latest Green Operation ‘GO’ mode circuitry, the XC6705/06 is the ideal solution for many applications.  Whether it is a battery powered design or a product with a 12 V supply, this new family of LDO Voltage Regulators offers several beneficial features to help designers maximise system performance whilst conserving energy through adaptive power consumption:

Package Options

The XC6705 series is available in SOT-25 & USP-4 packages which both have a chip enable pin meaning that the LDO can be turned ON/OFF. The XC6706 is available in a SOT-89 package and has no chip enable pin and therefore is always ON:
