GO Compatible HS LDO Voltage Regulator
This product is not recommended for new designs, please use XC6217
The XC6207 series are low noise, high speed, LDO regulators with a green operation (GO) function which automatically reduces quiescent current at low output loads down to a tiny 5.5μA (typ.). Performance features of the series includes fast ripple rejection (70dB @ 1kHz) and low dropout voltage (135mV @ 100mA). The series includes a voltage reference, error amplifier, current limiter, phase compensation circuit plus a driver transistor. Green operation (GO) automatically switches between a high speed mode (HS) and a power save mode (PS) depending upon the load current level. The switch point is fixed internally.
High-speed only operation can be enabled by providing a high level signal to the GO pin, this allows the user to select the most appropriate operating mode for the application.
By inputting a low signal to the CE pin, the IC will be put into an OFF state, with a stand-by current of 0.1uA. In this state with the XC6207B, a short will be created via the internal switch located between the VOUT and VSS pins and this enables the stored charge at the output capacitor (CL) to be discharged enabling the VOUT pin to quickly return to the VSS level.
The output stabilization capacitor (CL) is also compatible with low ESR ceramic capacitors. The constant current limit circuit and current limit's fold-back circuit also operate as a short circuit protection for the output current and the output pin.
