Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

1.2.2
MCP1711 Overview
The MCP1711 device has been developed to provide ultra-low power applications with
a precise, regulated rail. It 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 about ±50 ppm/°C. Line
regulation is ±0.01%/V typical at +25°C.
2015 Microchip Technology Inc.
DS50002411A-page 11
MCP1711 Demonstration Board User’s Guide
The output voltages available for the MCP1711 device 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 used. The MCP1711 is compatible with low equivalent series
resistance (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 increases beyond
the MCP1711 load rating, the output current and output voltage will foldback toward
80 mA (typical) at about 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.

WHAT IS THE MCP1711 DEMO BOARD?
The MCP1711 Demo Board has been developed to demonstrate the capabilities of the
MCP1711 device with two voltage options and two package options:
• 1.8V in 5-Lead SOT-23
• 3.3V in 4-Lead 1x1 UQFN
Two circuits have been developed on the same board; they are electrically isolated and
can be tested independently. Thus the MCP1711 Demo Board is meant to show how
the MCP1711 device operates over a wide input voltage and load range.
Test points for input voltage and output voltage are provided to demonstrate the
capability of the demo board over the entire range, allowing the board to be connected
directly to a system.
The MCP1711 device can also be used without any input and output capacitors. To test
the capacitorless feature, remove the CIN and COUT capacitors from the desired circuit
using a soldering iron set to 400°C or a hot-air gun set to the same temperature. Take
care not to damage the LDOs in the process.
CAUTION
Removing the capacitors can damage them. For further usage, it is recommended to
resolder untouched capacitors.

Product Overview
The board is equipped with a 3-pin 2.54 mm male header to allow the MCP1711 to be
shut down or enabled with a jumper. To enable the device without an external signal,
connect a jumper between the pins indicated by the EN silkscreen.
The MCP1711 can also be enabled and disabled by applying an external voltage (VEN)
between the second and the third terminals of this header.

When VEN is higher than 0.91V, the MCP1711 is turned on. When the VEN voltage is
less than 0.38V, the device output is turned off.
It is strongly recommended not to leave the SHDN pin floating as this will cause output
voltage instability.
The MCP1711 Demo Board is designed to operate from 3.2V to 6.0V input voltage
when VR = 1.8V (SOT-23) and from 4.0V to 6.0V input voltage when VR = 3.3V
(1x1 UQFN) and regulate the output voltage to the specified value over the entire
current and temperature range.
The MCP1711 Demo Board was designed using small surface-mount components to
show power supply size for ultra-low power, high-current applications.
If space-saving is a priority, the MCP1711 is stable even if an output capacitor in not
present, reducing cost and board area.

GETTING STARTED
The following sections describe how to use the MCP1711 Demo Board to fully evaluate
and demonstrate the capabilities of the MCP1711 device.
2.2
POWER INPUT AND OUTPUT CONNECTIONS
2.2.1
Powering the MCP1711 Demo Board
The MCP1711 Demo Board is fully assembled, tested and ready to begin evaluating
the MCP1711device.
Apply positive input voltage to the desired VIN terminal on the demonstration board and
its return to the corresponding GND terminal. The maximum input voltage should not
exceed 6.0V.
An electronic load or resistive load can be used to evaluate the MCP1711 Demo Board
or the intended system load can be connected. Electronic loads can attempt to sink
current at 0V during start-up, therefore a resistive load or constant resistance electronic
load is recommended for start-up evaluation. Do not use the electronic load in
Constant Current mode.
Connect the positive voltage terminal of the load at the VOUT terminal on the
demonstration board, and connect the negative, or return side of the load, to the
corresponding GND terminal.

2.3
BOARD TESTING
To test the board, follow these steps:
1. Apply input voltage.
2. If the EN jumper is connected as indicated in Figure 1-2 in Chapter 1. “Product
Overview”, the output voltage of MCP1711 will start to rise and it will stabilize
after some time, depending on the output current.
3. Adjusting the input voltage and load should not cause the output to vary over the
operating range of the linear regulator by more than a few tens of mV, in a steady
state condition.
