Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ
What is the function of the EN pin?
The EN pin controls the regulator state; driving it high enables the output, while pulling it low activates shutdown mode.
How is short circuit protection implemented?
The device includes fold-back short circuit protection that clamps the output current to approximately 60mA when VOUT is shorted to GND.
