Microchip Technology MCP1725T-1202E/MC

Description
The MCP1725 is a 500 mA Low Dropout (LDO) linear regulator that provides high current and low output voltages in a very small package. It comes in a fixed (or adjustable) output voltage version, with an output voltage range of 0.8V to 5.0V. The 500 mA output current capability, combined with the low output voltage capability, makes the MCP1725 a good choice for new sub-1.8V output voltage LDO applications that have high current demands.
The MCP1725 is stable using ceramic output capacitors that inherently provide lower output noise and reduce the size and cost of the entire regulator solution. Only 1 uF of output capacitance is needed to stabilize the LDO.
Using CMOS construction, the quiescent current consumed by the MCP1725 is typically less than 120 μA over the entire input voltage range, making it attractive for portable computing applications that demand high output current. When shut down, the quiescent current is reduced to less than 0.1 μA.
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 200 μs to 300 ms.
The overtemperature and short circuit current-limiting provide additional protection for the LDO during system fault conditions.
