General Description
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 tran-
sient responses, the output capacitor should be added.
The MCP1711 is compatible with low ESR ceramic
output capacitors.
Overcurrent limit and short-circuit protection embed-
ded 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 fold-
back toward 80 mA (typical) at approximately 0V out-
put. When the load impedance increases and returns to
the rated load, the MCP1711 will follow the same fold-
back 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 consump-
tion 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 x 1 mm UQFN and the 5-lead SOT-23, which makes
the device ideal for small and compact applications.

Note 1: The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable
junction temperature, and the thermal resistance from junction to air (i.e., TA, TJ, JA). Exceeding the max-
imum allowable power dissipation will cause the device operating junction temperature to exceed the
maximum +125°C rating. Sustained junction temperatures above +125°C can impact the device reliability.
2: The device is mounted on one layer PCB with minimal copper that does not provide any additional cooling.
