onsemi Voltage Regulators - Linear KA79L05AZTA-ON

The KA79L05AZTA-ON is a 3-terminal linear voltage regulator designed to provide a fixed output voltage of -5 V with a maximum output current of 100 mA. It features internal thermal overload protection and short-circuit current limiting, ensuring reliable operation under various conditions. The device operates within an input voltage range of -20 V to -30 V and has a specified operating temperature range of 0°C to +125°C. The output voltage tolerance is ±5%, with line regulation of 15 mV to 150 mV depending on the input voltage range, and load regulation of 20 mV to 60 mV for output currents between 1.0 mA and 100 mA. The quiescent current is typically between 2.0 mA and 5.5 mA at 25°C. The KA79L05AZTA-ON is packaged in a TO-92 form factor, making it suitable for various applications where space is a consideration. Engineers should consider this regulator for projects requiring a stable negative voltage supply with built-in protection features and minimal external component requirements.
