L78L33ACUTR  

Linear & Switching Voltage Regulators

The L78L33ACUTR is a linear voltage regulator integrated circuit (IC) manufactured by STMicroelectronics. It is part of the L78L family of low-dropout (LDO) voltage regulators, which are designed to provide a stable and reliable output voltage from a varying input voltage source.

Description:

The L78L33ACUTR is a fixed-output, low-dropout voltage regulator with an output voltage of 3.3V. It is available in a small SOT-89 package, making it suitable for space-constrained applications. The regulator has a quiescent current of typically 70µA, which helps to minimize power consumption in battery-powered devices.

Features:

1. Fixed output voltage of 3.3V
2. Low dropout voltage (max 300mV at full load)
3. High input voltage range (up to 30V)
4. Low quiescent current (typically 70µA)
5. Short-circuit protection
6. Overload protection
7. Thermal shutdown protection
8. SOT-89 package for compactness

Applications:

The L78L33ACUTR is suitable for a wide range of applications that require a stable 3.3V output voltage. Some common applications include:

1. Power supply for microcontrollers and other digital circuits
2. Voltage regulation in battery-powered devices
3. Voltage conversion in power supply circuits
4. Voltage stabilization for sensitive analog circuits
5. Providing a stable voltage reference for precision circuits

The L78L33ACUTR's low dropout voltage, wide input voltage range, and compact package make it an ideal choice for applications where space is limited, and a stable 3.3V output is required. Its built-in protection features also help ensure the reliability and longevity of the system in which it is used.
