Instructions for Use
Circuit Design:
- Connect the input voltage to the
VIN
pin. - Connect the output voltage to the
VOUT
pin. - Ensure the
GND
pin is connected to the ground. - The
SHDN
pin can be used to enable or disable the regulator. Connect it toGND
to disable and leave it open or connect toVIN
to enable. - The
BYP
pin is optional and can be used for additional filtering. Connect a capacitor betweenBYP
andGND
if needed.
- Connect the input voltage to the
Capacitors:
- Use a 1 μF ceramic capacitor on the input side (between
VIN
andGND
). - Use a 1 μF ceramic capacitor on the output side (between
VOUT
andGND
).
- Use a 1 μF ceramic capacitor on the input side (between
Thermal Considerations:
- Ensure adequate heat dissipation if operating at high output currents.
- Place the device on a PCB with sufficient copper area to help dissipate heat.
Power-Up Sequence:
- Ensure the input voltage rises smoothly and does not exceed the maximum rating.
- Avoid sudden changes in load to prevent instability.
Storage:
- Store in a dry environment to prevent moisture damage.
- Handle with care to avoid static discharge, which can damage the device.
Testing:
- Measure the output voltage at
VOUT
with respect toGND
to ensure it is within the expected range. - Check the quiescent current by measuring the current drawn from
VIN
whenVOUT
is not loaded.
- Measure the output voltage at
Safety:
- Do not exceed the maximum ratings specified in the datasheet.
- Use appropriate fuses or circuit breakers to protect against overcurrent conditions.
