STMicroelectronics L4993
The L4993 is a monolithic integrated 5 V Voltage regulator 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 L4993 is protected against short circuit and an over-temperature protection switches off the device in case of extremely high power dissipation.| Part No. | L4993 |
