MCP1827ST-5002E/EB

The MCP1827S is a 1.5A Low Dropout (LDO) linear regulator that provides high current and low output voltages. The MCP1827S is a 3-pin fixed voltage version. The MCP1827S is based upon the MCP1727 LDO device. The MCP1827S 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 µF of output capacitance is needed to stabilize the LDO. Using CMOS construction, the quiescent current consumed by the MCP1827S is typically less than 120 µA over the entire input voltage range, making it attractive for portable computing applications that demand high output current. The PWRGD delay is internally fixed at 200 µs (typical). The overtemperature and short circuit current-limiting provide additional protection for the LDO during system Fault conditions.
