Instructions for KD221K05

1. Power Supply Connection:

   • Connect the VDD pin to the positive terminal of your power supply.
   • Ensure the supply voltage is within the specified range (2.7V to 5.5V).

2. Output Configuration:

   • The output pin can supply up to 300mA of current. Ensure that the load does not exceed this limit.

3. Enable Pin (VEN):

   • Apply a voltage greater than 0.9V to the enable pin to activate the device.
   • To disable the device, apply a voltage less than 0.9V or leave it floating.

4. Current Consumption:

   • In active mode, the device consumes approximately 1.5渭A to 3.0渭A.
   • In shutdown mode, the current consumption drops to around 0.1渭A to 0.5渭A.

5. Thermal Considerations:

   • Ensure the operating temperature remains within -40掳C to 85掳C.
   • For storage, keep the device within -65掳C to 150掳C.

6. Dropout Voltage:

   • Be aware of the dropout voltage, which ranges from 200mV to 400mV under rated load conditions. This affects the minimum input voltage required to maintain regulation.

7. Handling Precautions:

   • Handle with care to avoid damage from electrostatic discharge (ESD).
   • Follow standard precautions for handling electronic components.
