The REG102UA-3.3 is a linear voltage regulator from Quarktwin Technology Ltd. designed to provide a fixed output voltage of 3.3V with a maximum output current of 250mA. It features a low dropout voltage of 150mV at full load, which enhances efficiency in battery-powered applications. The device operates with a typical ground pin current of 600¬µA and drops to 10nA when disabled, making it suitable for low-power applications. This regulator does not require an output capacitor for stability, simplifying design and reducing component costs. It offers fast transient response and low output noise, typically 28¬µVrms, which is beneficial for sensitive electronic devices. The REG102UA-3.3 includes built-in thermal protection and foldback current limiting to safeguard against overload conditions. The operating temperature range is specified from -40¬8C to +85¬8C, ensuring reliability in various environments. It is available in an 8-pin SOIC package, making it suitable for compact designs. This product is ideal for use in portable communication devices, personal digital assistants, and other battery-operated equipment.
