The voltage regulator uses a p-channel MOS transistor as a regulating element. With this structure a verylow dropout voltage at current up to 150mA is obtained. The output voltage is regulated up to transientinput supply voltage of 40V. No functional interruption due to over-voltage pulses is generated.The voltage Regulator is always active and not depending on the state of WEn input pin.A short circuit protection to GND is provided.
