L78L06ACZ-AP

The L78L06ACZ-AP is a low-dropout linear regulator designed for battery-powered portable devices. It features a wide input voltage range and low quiescent current (typical 2.2 mA) that makes it ideal for powering typical microcontroller circuits. Furthermore, its low-dropout voltage ensures optimal performance even with lower input voltages.

The L78L06ACZ-AP linear regulator is designed to provide a precise output voltage and current over a wide range of current and temperature. The output of the regulator is achieved by controlling the base-emitter voltage of the device’s pass transistor. This voltage is controlled by setting the control-input voltage, VIN, to a value that is above the output voltage.

The L78L06ACZ-AP offers two settings (EN and GND) for output voltage. By connecting the EN pin to GND, the regulator’s output is set to a predefined output voltage. This fixed output voltage is set to 5V by default and can also be adjusted using external resistors. Alternatively, by connecting the EN pin to another voltage (VIN-1V), a second output voltage is enabled. This second output voltage is equal to the voltage at the EN pin minus 1V.

The L78L06ACZ-AP also provides an advanced over-temperature protection circuit. This feature will automatically shut down the IC if the temperature of the device exceeds the predetermined maximum, thus protecting the device from potential overheating damage. Additionally, the output voltage of the regulator is self-limiting and can achieve short-circuit protection as well.

In summary, the L78L06ACZ-AP is an advanced low-dropout linear voltage regulator designed for low-current battery-powered applications. It features a wide operating temperature range, low quiescent current, advanced features such as over-temperature protection, and can be configured to provide a second adjustable output voltage. With its highly integrated features and low-cost solution, the L78L06ACZ-AP is an ideal choice for embedded systems.
