GENERAL DESCRIPTION
The XC6225 series is a high accuracy, low noise, and low dropout CMOS LDO regulator. The series includes a reference voltage source, an error amplifier, a driver transistor, a current limiter, and a phase compensation circuit.
The CE function enables the entire circuit to be turned off by a low level input signal to the CE pin. In this stand-by state, the XC6225B series can discharge the electric charge stored at the output capacitor through the internal auto-discharge switch, and as a result the VOUT pin quickly returns to the VSS level. The output stabilization capacitor (CL) is also compatible with low ESR ceramic capacitors. Output voltage is selectable in 0.05V increments within a range of 0.8V~5.0V. The current limit fold-back circuit works as a short circuit protection as well as the output current limiter. The series achieves a fast response with only 25μA of low power consumption. The current limit is set to 50mA (TYP.) so that the device is optimized to protect the circuit from over-current. It is ideally suited for applications requiring 30 mA or less.
A small USP-4 package makes high density mounting possible.
