Introduction

AI Translation

The MCP1827/MCP1827S is a 1.5A Low Dropout (LDO) linear regulator that provides high current and low output voltages. The MCP1827 comes in a fixed or adjustable output voltage version, with an output voltage range of 0.8V to 5.0V. The 1.5A output current capability, combined with the low output voltage capability, make the MCP1827 a good choice for new sub-1.8V output voltage LDO applications that have high current demands. The MCP1827S is a 3-pin fixed voltage version.

The MCP1827/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 1μF of output capacitance is needed to stabilize the LDO.

Using CMOS construction, the quiescent current consumed by the MCP1827/MCP1827S is typically less than 120μA over the entire input voltage range, making it attractive for portable computing applications that demand high output current. The MCP1827 versions have a Shutdown (SHDN) pin. When shut down, the quiescent current is reduced to less than 0.1μA.

On the MCP1827 fixed output versions 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). The PWRGD delay is internally fixed at 200μs (typical).

The overtemperature and short circuit current-limiting provide additional protection for the LDO during system Fault conditions.
