onsemi Voltage Regulators - Linear, Low Drop Out (LDO) Regulators CS8151D2G

The CS8151D2G is a low dropout linear voltage regulator designed to provide a stable 5.0 V output at a maximum load current of 100 mA. It features a typical dropout voltage of 400 mV and operates with a low quiescent current of 400 µA, making it suitable for battery-operated devices. The output voltage accuracy is within ±2%, ensuring reliable performance in various applications. This regulator includes integrated microprocessor control functions such as Watchdog, Wake Up, and RESET. The Wake Up function allows the microprocessor to exit Sleep mode, while the Watchdog monitors the microprocessor's activity, ensuring it sends a signal within the expected timeframe. The RESET function operates independently of the input voltage and can trigger under specific conditions, such as during power-up or if the output voltage falls below regulation limits. The CS8151D2G is equipped with several protection features, including thermal shutdown, short circuit protection, and the ability to withstand peak transient voltages of up to 74 V, making it suitable for automotive applications. It is available in a Pb-free SO-14L package, ensuring compliance with environmental standards.
