Detailed description

L78L05ABUTR IC

The L78L05ABUTR is a precise, positive linear voltage regulator from the L78L series, designed as an efficient alternative to larger regulators in low-current applications. This three-terminal SOT-89 package component provides a stable 5V output, forming the basis for electronic projects that require local voltage regulation directly on the PCB. With built-in current limiting and thermal protection, the device offers high reliability even under challenging operating conditions.

Key Features and Specifications of L78L05ABUTR

The L78L05ABUTR regulator from STMicroelectronics features excellent line and load regulation, making it ideal for sensitive analog and digital circuits. The SOT-89 package allows efficient heat dissipation while maintaining compact dimensions. The most important technical parameters of this regulator include:

  • Output Voltage (Fixed): 5V.
  • Maximum Output Current (Io): 100mA.
  • Maximum Input Voltage (Vi): up to 30V.
  • Line Regulation: typically 50mV (for Vi from 7V to 20V).
  • Dropout Voltage (Vd): typically 1.7V.
  • Operating Temperature Range: -40°C to +125°C.
  • Package: SOT-89, designed for surface-mount (SMD) assembly.

Integrated safety features, including thermal shutdown during overload, make this product extremely durable and protect the rest of the circuitry from power failures.

Typical Applications of L78L05ABUTR

Due to its current characteristics and compact size, the L78L05ABUTR regulator is most often used in circuits requiring stable voltage with low noise. Common application areas include:

  • Local power supply for microcontrollers and logic modules in embedded systems,
  • Reference voltage stabilization for analog-to-digital converters (ADC),
  • Control and automation circuits powered from higher-voltage buses,
  • Consumer electronics, including chargers, power supplies, and portable devices,
  • Communication interfaces and low-power measurement systems.
