Introduction

AI Translation

The MCP1826/MCP1826S is a 1000 mA Low Dropout (LDO) linear regulator that provides high-current and low-output voltages. The MCP1826 comes in a fixed or adjustable output voltage version, with an output voltage range of 0.8V to 5.0V. The 1000 mA output current capability, combined with the low-output voltage capability, make the MCP1826 a good choice for new sub-1.8V output voltage LDO applications that have high current demands. The MCP1826S is a 3-pin fixed voltage version. The MCP1826/MCP1826S 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 MCP1826/MCP1826S 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 MCP1826 versions have a Shutdown (SHDN) pin. When shut down, the quiescent current is reduced to less than 0.1 μA. On the MCP1826 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 200 μs (typical). The overtemperature and short circuit current-limiting provide additional protection for the LDO during system Fault conditions.
