Power Solution (LDO) - XC6206

The XC6206 series is a high-precision, low-power three-terminal positive voltage regulator that provides high current and minimal dropout voltage. It consists of a current limiting circuit, a driver transistor, a precision reference voltage, and an error correction circuit. This series is compatible with low ESR ceramic capacitors. The output voltage can be selected in the range of 1.2V to 5.0V with an increment of 0.1V.

In this article, we have chosen the XC6206 series from TOREX, in SOT-23 package. Other manufacturers may have similar models that can be used as substitutes, but please verify the detailed parameters.
