onsemi Voltage Regulators - Linear FAN1117AD33X

The FAN1117AD33X is a low dropout linear voltage regulator capable of delivering up to 1A output current. It features a fixed output voltage of 3.3V and is designed for applications requiring efficient voltage regulation with minimal input-output voltage differential. The device exhibits a typical load regulation of 0.05% and a dropout voltage of approximately 1.2V at full load, making it suitable for low voltage applications where transient response is critical. This regulator includes on-chip thermal limiting for protection against overheating and has a trimmed current limit to ensure specified output current under various conditions. The FAN1117AD33X is available in standard TO-252 packaging, which facilitates easy integration into various circuit designs. It is particularly useful in applications such as post regulators for switching supplies, battery chargers, and motherboard clock supplies. The maximum input voltage is rated at 18V, with a junction temperature range of 0¬8C to 125¬8C, ensuring reliable operation in diverse environments.
