Adjustable output voltage: 2.5–73 V (positive output)

Output current: up to 500 mA

Topology: buck (step‑down)

Output type: adjustable, single output

Synchronous rectifier: no (use external Schottky diode)

Package: 8‑VSSOP (also referenced as 8‑TSSOP / 8‑MSOP, 3.00 mm width)

Operating junction temperature: −40°C to +125°C

Mounting: surface mount (SMD)

RoHS: ROHS3 compliant, lead‑free

Category: Integrated Circuits (ICs) → PMIC – Voltage Regulators – DC‑DC Switching Regulators

Packaging

Type: 8‑VSSOP (also noted as 8‑TSSOP / 8‑MSOP narrow)

Material: lead‑free matte‑tin plated copper leadframe with epoxy mold compound (RoHS3 compliant)

Size: narrow body, approximately 3.00 mm width; low‑profile package suited for compact PCBs

Pin configuration: 8 leads; typical functions include input supply, switch node, ground, feedback, enable/UVLO, and bias pins. Refer to the datasheet for the exact pinout and pin functions.

Thermal characteristics: junction operating range −40°C to +125°C (TJ). Actual thermal resistance depends on PCB copper area and airflow; use adequate copper planes and follow layout guidance in the datasheet for heat dissipation.
