REG710 SBAS221G – DECEMBER 2001 – REVISED JANUARY 2009........................................................................................................................................... www.ti.com THEORY OF OPERATION The REG710 regulated charge pump provides a regulated output voltage for input voltages ranging from less than the output to greater than the output. This is accomplished by automatic mode switching within the device.

REG710 www.ti.com........................................................................................................................................... SBAS221G – DECEMBER 2001 – REVISED JANUARY 2009 PROTECTION The regulator has thermal shutdown circuitry that protects it from damage caused by overload conditions. The thermal protection circuitry disables the output when the junction temperature reaches approximately +160°C, allowing the device to cool.

REG710 SBAS221G – DECEMBER 2001 – REVISED JANUARY 2009........................................................................................................................................... www.ti.com EFFICIENCY LAYOUT The efficiency of the charge pump regulator varies with the output voltage version, the applied input voltage, the load current, and the internal operation mode of the device. Large transient currents flow in the VIN, VOUT, and GND traces.
