XC6504 Series Small Voltage Regulators

Most LDOs require that an output capacitor CL be connected to the output pin to stabilize the output voltage. This is because the output capacitance CL is used for phase-compensation and if there is no CL, the IC becomes unable to perform phase-compensation, and abnormal oscillation occurs in the output. For this reason, it is common practice to connect a capacitor exclusively for the LDO near the LDO output pin.

However, the XC6504 series from Torex has an internal phase-compensation circuit that makes it possible to obtain a stable output voltage without CL. The operation is also stable if an output capacitance is temporarily connected, and even in cases where a bypass capacitor is connected to an IC on the load side, the XC6504 series can be used without any limitations due to the capacitor.
