MIC94310 Evaluation Board
200mA LDO with
Ripple Blocker™ Technology
General Description
The MIC94310 is a 200mA Low Dropout (LDO)
regulator that provides high power supply ripple
rejection (PSRR). This is important for applications
where switching noise cannot be tolerated by sensitive
downstream circuits such as in RF applications. The
MIC94310 maintains high power supply ripple rejection
(PSRR) with input voltage operating near the output
voltage level to improve overall system efficiency.
The MIC94310 operates from an input voltage of 1.8V to
3.6V.
Datasheets and support documentation can be found on
Micrel’s web site at www.micrel.com.
Requirements
The MIC94310 evaluation board requires an input power
supply that is capable of delivering greater than 400mA
at a voltage range of 1.8V to 3.6V. The output load can
be either active or passive.
Precautions
The MIC94310 evaluation board does not have reverse
polarity protection. Applying a negative voltage to the
V_IN terminal may damage the device.
Getting Started
• Connect an External Supply to V_IN. Apply the
desired input voltage to the V_IN and ground terminal
of the evaluation board, paying careful attention to
polarity and supply voltage (1.8V ≤ V_IN ≤ 3.6V).
• Enable/Disable the MIC94310. The evaluation
board is supplied with 100kΩ pull-up resistor to V_IN
for default on state. To disable the output, simply
jumper the EN terminal to ground.
• Connect the Load. Connect the load to the V_OUT
terminal and the ground terminal. The load can be
either a passive (resistor) or active (electronic load).
Be sure to monitor the output voltage at the V_OUT
terminal.
