Torex Semiconductor Ltd has released the XC6220 series of 1A output high-speed CMOS LDO regulator.

The XC6220 achieves high precision, low noise and low dropout while providing up to 1A output current. It also features ultralow dropout voltage at 60mV@300mA, thereby extending battery life.

The device is equipped with the environmentally friendly "Green Operation" function which can automatically reduce supply current by switching the IC into a low #LINKKEYWORD1# (power save) mode when output current falls to below a certain level. The switching point is fixed internally within the IC. As load current demand increases, the XC6220 automatically and quickly switched back to high speed mode. In addition, the XC6220 also provides over current protection and thermal shutdown protection.

Application of the small USP-6 package (1.8mm x 2mm x 0.6mm) with effective heat radiation contributes to small foot print design of circuits. SOT-25 and SOT-89-5 packages are also available.
