onsemi Voltage Regulators - Linear CS8129YDWR16G

The CS8129YDWR16G is a linear voltage regulator from Quarktwin Technology Ltd. designed to provide a fixed output of 5.0 V with a maximum output current of 750 mA. It features a low dropout voltage of 0.6 V at 0.5 A, making it suitable for applications requiring efficient voltage regulation. The device includes a reduced RESET threshold of 4.2 V, allowing compatibility with 4.0 V microprocessors and enabling operation under low battery conditions. The RESET function is externally programmable using a discrete RC network, with a delay time that can be adjusted based on the application needs. The CS8129 is equipped with comprehensive fault protection mechanisms, including reverse battery, overvoltage, short circuit, and thermal shutdown protections. It can withstand voltage transients from -50 V to +60 V, ensuring reliability in various operating conditions. The device is housed in a 16-lead surface mount package, making it suitable for compact designs.
