Description
:
The MCP1755/MCP1755S is a family of CMOS Low Dropout (LDO) voltage regulators that can deliver up to 300 m A of current while consuming only 68.0 µA of quiescent current (typical). The input operating range is specified from 3.6V to 16.0V, making it an ideal choice for four to six primary cell battery-powered applications, 12V mobile applications and one to three-cell Li-Ion-powered applications.
The MCP1755/MCP1755S is capable of delivering 300 m A with only 300 m V (typical) of input-to-output voltage differential. The output voltage tolerance of the MCP1755 is typically +0.85% at +25°C and ±2.0% maximum over the operating...
