Description
General part information
L4989 Series
The L4989M and L4989MD are monolithic integrated 5 V voltage regulators with a low drop voltage at currents up to 150 mA.
The output voltage regulating element consists in a p-channel MOS and the regulation is performed regardless of input voltage transients up to 40 V. The high precision of the output voltage is obtained with a pre-trimmed reference voltage.
The devices are protected against short circuit and an overtemperature protection switches off the devices in case of extremely high power dissipation.
