MCP1711T-33I/OT

The MCP1711 is a highly accurate CMOS low dropout (LDO) voltage regulator that can deliver up to 150 mA of current while consuming only 0.6 μA of quiescent current (typical). The input operating range is specified from 1.4V to 6.0V, making it an ideal choice for mobile applications and one - cell Li - Ion powered applications.

The MCP1711 is capable of delivering 150 mA output current with only 0.32V (typical) for VR = 5.0V, and 1.41V (typical) for VR = 1.2V of input - to - output voltages differential. The output voltage accuracy of the MCP1711 is typically ± 0.02V for VR < 2.0V and ±1% for VR ≥ 2.0V at +25°C. The temperature stability is approximately ±50 ppm/°C. Line regulation is ±0.01%/V typical at +25°C.

The output voltages available for the MCP1711 range from 1.2V to 5.0V. The LDO output is stable even if an output capacitor is not connected, due to an excellent internal phase compensation. However, for better transient responses, the output capacitor should be added. The MCP1711 is compatible with low ESR ceramic output capacitors.

Overcurrent limit and short - circuit protection embedded into the device provide a robust solution for any application.

The MCP1711 has a true current foldback feature. When the load decreases beyond the MCP1711 load rating, the output current and output voltage will foldback toward 80 mA (typical) at approximately 0V output. When the load impedance increases and returns to the rated load, the MCP1711 will follow the same foldback curve as the device comes out of current foldback.

If the device is in Shutdown mode, by inputting a low - level signal to the SHDN pin, the current consumption is reduced to less than 0.1 μA (typically 0.01 μA). In Shutdown mode, if the output capacitor is used, it will be discharged via the internal dedicated switch and, as a result, the output voltage quickly returns to 0V.

The package options for the MCP1711 are the 4 - lead 1×1 mm UQFN and the 5 - lead SOT - 23, which make the device ideal for small and compact applications.
