Instructions for Use:

1. Circuit Design: Ensure the input voltage is within the specified range (2.7V to 5.5V). For adjustable output versions, use external resistors to set the desired output voltage.
2. Capacitors: Place a 1μF ceramic capacitor on both the input and output for stability. For better transient response, a larger capacitor can be used.
3. Enable Pin: The enable pin allows control of the regulator’s operation. Apply a high signal to turn on the regulator; apply a low signal or leave it unconnected to turn off the regulator.
4. Thermal Considerations: Ensure adequate heat dissipation if operating near the maximum current and input voltage limits.
5. Layout: Keep the layout compact with short leads between the regulator and capacitors to minimize noise and improve stability.
6. Discharge Path: When the enable pin is low, an internal discharge path helps quickly discharge the output capacitor, reducing power consumption in standby mode.
