The STMicroelectronics ST1S09PUR is a versatile DC-DC switching regulator designed for step-down (buck) conversion. It features an adjustable output voltage capability, allowing for flexible power supply designs. The device can handle an output current of up to 2A and operates with an input voltage range from 2.7V to 6V.
Key electrical specifications include a switching frequency of 1.5MHz, enabling efficient power conversion. The output voltage is adjustable, with a minimum of 0.8V and a maximum of 5.22V. The regulator is designed with a synchronous rectifier for improved efficiency.
Packaged in a compact 6-DFN (3x3) exposed pad surface-mount package, the ST1S09PUR is suitable for applications where space is constrained. It operates within a temperature range of -30°C to 85°C (TJ). The positive output configuration and step-down topology make it a suitable choice for various power management applications.
Environmental compliance includes RoHS3 status as compliant, MSL 1, and REACH unaffected. The mounting type is surface mount, and it is available in Tape & Reel or Cut Tape packaging.
