The device offers a dropout voltage of only 300 mV (typical) at full load current, and a quiescent current of just 140 µA (typical). In addition, the MCP1727 offers a shutdown feature that allows it to be enabled and disabled by system logic. More efficient and cost-effective designs are possible because the device is stable with a ceramic output capacitor.
The MCP1727 also has an output voltage sense pin that is used to compensate for output voltage changes due to losses in the output bond wire, resulting in faster, more accurate output voltage regulation. The power good output with user programmable delay gives designers flexibility in power scheduling for a range of applications.
Microchip’s MCP1726 1A LDO Evaluation Board (Part Number MCP1726EV) can also be used to support development using the 1.5A MCP1727.
