The MCP1725-3302E/MC is a 3.3V fixed output low-dropout (LDO) Linear Regulator provides high current and low output voltage. The 500mA output current capability, combined with the low output voltage capability, make the device a good choice for applications that have high current demands. The device is stable using ceramic output capacitors that inherently provide lower output noise and reduce the size of the entire regulator solution. Only 1µF of output capacitance is needed to stabilize the LDO. Using CMOS construction, the quiescent current consumed by the device is typically less than 120µA over the entire input voltage range. When shut down, the quiescent current is reduced to less than 0.1µA. The scaled-down output voltage is internally monitored and a power good (PWRGD) output is provided when the output is within 92% of regulation (typical). An external capacitor can be used on the CDELAY pin to adjust the delay from 200µs to 300ms.
