Optical-drive power management in a compact QFN
The STODD03PQR is a dedicated Blu-ray power management IC from STMicroelectronics, built for the specific power sequencing and regulation demands inside optical disc drives. It integrates multiple supply rails and control logic into a single 16-VQFN Exposed Pad package (4x4 mm), saving board area compared to a discrete regulator array. Rated for a 4V to 6V input supply and drawing 1.6 mA quiescent current, the part stays within the power budget of a slim optical drive module. The -25°C to 125°C operating range covers the internal ambient of a consumer-electronics chassis with margin for the laser diode driver heat.
Active production, ROHS3, and package options
It is ROHS3 compliant, so it passes the EU RoHS exemption roll-up without a certificate of analysis headache. Available in Tape & Reel (TR) or Cut Tape (CT) for the 16-VQFN Exposed Pad package. The QFN's exposed paddle needs a thermal via array under the pad to pull heat into the inner-layer copper pour; the datasheet's recommended land pattern is the reference for that layout.
