MIC5365/6 Evaluation Board
High Performance Single 150mA LDO
General Description
The MIC5365/6 is an advanced general purpose linear
regulator. The MIC5365/6 is capable of sourcing 150mA
output current with high PSRR and low output noise. When
the MIC5366 is disabled an internal resistive load is
automatically applied to the output to discharge the output
capacitor. Both the MIC5365 and MIC5366 are available in
a 4-pin 1mm x 1mm Thin MLF®, as well as the SC-70-5
packages.
The MIC5365/6 linear regulator is easy to use. A small
output capacitance of only 1µF for the output is required.
An input capacitor may be required when the power supply
is more than 4-inches away from the device. The
evaluation board includes an input capacitor of 10µF to
compensate for long inductive test leads.
Getting Started
1. Connect an external supply to VIN. Apply the
desired input voltage to the VIN (J1) and ground
terminal (J2) of the evaluation board, paying
careful attention to polarity and supply voltage
(2.5V ≤ VIN ≤ 5.5V). An ammeter may be placed
between the input supply and the VIN terminal to
the evaluation board. Ensure that the supply
voltage is monitored at the VIN terminal. Ammeter
and/or power lead resistance can reduce the
voltage supplied to the input.
Requirements
The MIC5365/6 evaluation board requires an input power
source that is able to deliver at least 200mA at a voltage
within the range of 2.5V to 5.5V. The output load can be
either active or passive.
Precautions
The evaluation board does not have reverse
protection. Applying a negative voltage to the VIN
may damage the device.
The MIC5365/6 evaluation board is tailored for
range input supply voltage. It should not exceed
the input.

2. Enable/Disable the MIC5365/6. The evaluation
board is set up for “Default Disable” with a 100k
pull down resistor on the enable pin (EN) to GND.
To enable the output, simply jumper the EN
terminal (J5) to the VIN terminal (J1). The enable
pin must be either pulled high or low for proper
operation. Removing the pull down resistor and
leaving the pin floating will cause the regulator to
operate in an indeterminate state.
3. Connect the load to the VOUT terminal (J3) and
ground terminal (J4). The load can be either a
passive (resistor) or active (electronic load). Be
sure to monitor the output voltage at the VOUT (J3)
terminal.
