XP POWER STR05S09 Switching Regulator

The STR05S09 from XP Power is a 0.5A regulated single-output switching regulator in a compact SMD package. It features a wide input voltage range of 11V to 32V and provides a fixed 9V output with a maximum current of 500mA. The regulator offers high efficiency, with a minimum of 92% and a maximum of 96%, and includes continuous short circuit protection with auto recovery. It has line regulation of ±0.2% (1.5V to 6.5V) and ±0.1% (9V to 15V), as well as load regulation of ±0.4% (1.5V to 6.5V) and ±0.25% (9V to 15V). The device supports a maximum capacitive load of 220μF, an input current of 5mA at no load, and a remote on/off control with an input current of 24V. Additional features include a trim range from 4.5V to 12.6V, ripple and noise levels of 30mV pk-pk (1.5V to 6.5V) and 40mV pk-pk (9V to 15V), an initial set accuracy of ±2%, switching frequency of 330kHz, dimensions of 15.3mm x 12.35mm x 9.24mm, weight of 1.7g, and an operational temperature range from -40°C to 100°C. Suitable applications include power management and industrial systems.
