Supply original L78L33ACD13TR, PMIC - Voltage Regulators - Linear, by STMicroelectronics

The L78L33ACD13TR is a fixed voltage linear voltage regulator manufactured by STMicroelectronics. It belongs to the L78 series of positive voltage regulators and is designed to provide a regulated output voltage of 3.3 volts.

Key Features:

• Fixed Output Voltage: The L78L33ACD13TR provides a fixed output voltage of 3.3 volts, making it suitable for powering electronic circuits requiring a stable voltage supply.

• Low Dropout Voltage: It features a low dropout voltage, meaning it can regulate the output voltage even when the input voltage is only slightly higher than the desired output voltage. This characteristic makes it efficient, especially in battery-powered applications.

• Low Quiescent Current: The regulator has a low quiescent current, which refers to the current consumed by the regulator itself when it is regulating the output voltage. Low quiescent current helps in minimizing power consumption, making it suitable for battery-operated devices.

• Internal Thermal Shutdown: The device includes internal thermal shutdown protection, which shuts down the regulator in case of excessive internal temperature, protecting the device from damage due to overheating.

• Internal Current Limiting: It incorporates internal current limiting to protect the regulator and the load from excessive currents.

• Wide Input Voltage Range: The regulator can accept a wide range of input voltages, typically from a few volts above the desired output voltage up to a maximum specified voltage.

• Short Circuit Protection: The L78L33ACD13TR includes short-circuit protection, which limits the output current in case of a short circuit condition, protecting the regulator and the connected components.

• Surface-Mount Package: It is available in a surface-mount package, allowing for easy integration onto printed circuit boards (PCBs) and enabling compact designs.

• RoHS Compliance: Manufactured in compliance with the Restriction of Hazardous Substances (RoHS) directive, ensuring environmental sustainability and compatibility with lead-free soldering processes.

Applications:

• Powering microcontrollers, sensors, and other digital ICs in various electronic devices
• Battery-powered applications such as portable devices, handheld instruments, and battery chargers
• Voltage regulation in consumer electronics, industrial automation, and automotive electronics
