L79L12ACUTR Description

Short technical summary and product information.

The STMicroelectronics L79L12ACUTR is a three-terminal negative voltage regulator with an output voltage of -12V. It can deliver an output current of up to 100mA, provided adequate heat-sinking is used. This regulator series features internal current limiting and thermal shutdown, making it highly reliable.

 

Designed for local or on-card regulation, the L79L12ACUTR helps eliminate noise and distribution problems associated with single-point regulation. It is suitable for use with power pass elements to create high-current voltage regulators. The device offers an effective output impedance improvement and lower quiescent current compared to traditional Zener diode/resistor combinations.

 

This component is available in a SOT-89-3 surface-mount package. It operates within a temperature range of 0°C to 125°C and includes protection features against over-temperature and short circuits. The regulator has a PSRR of 42dB at 120Hz.
