Product Introduction
The MCP1755/1755S is a family of CMOS low-dropout (LDO) voltage regulators that can deliver up to 300 mA of current while consuming only 68.0 μA of quiescent current (typical). The input operating range is specified from 3.6 V to 16.0 V, 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 MCP1755/1755S is capable of delivering 300 mA with only 300 mV (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 junction temperature range of -40°C to +125°C. Line regulation is ±0.01% typical at +25°C.
Output voltages available for the MCP1755/1755S range from 1.8V to 5.5V. The LDO output is stable when using only 1 μF of output capacitance. Ceramic, tantalum or aluminum electrolytic capacitors may all be used for input and output. Overcurrent limit and overtemperature shutdown provide a robust solution for any application.
The MCP1755/1755S family has a true current foldback feature. When the load impedance decreases beyond the MCP1755/1755S load rating, the output current and voltage will gracefully foldback towards 30 mA at about 0V output. When the load impedance increases and returns to the rated load, the MCP1755/1755S will follow the same foldback curve as the device comes out of current foldback.
Package options for the MCP1755 include the SOT-23-5, SOT-223-5 and 8-lead 2×3 DFN.
Package options for the MCP1755S device include the SOT-223-3 and 8-lead 2×3 DFN.
