Charge-pump regulator for low-power rails
The REG711EA-2.5/2K5: The charge-pump topology uses no inductor, which keeps the BOM count low and the radiated noise profile predictable — a consideration for sensitive analog or RF front-ends sharing the same board.
Switching frequency and temperature grade
Switching at 1 MHz, the part's output ripple falls into a frequency band where downstream LDOs or filters can attenuate it without large passives. The single fixed output at 2.5 V is set internally; no external resistor divider is needed. The positive output configuration and the absence of synchronous rectification mean the part relies on external Schottky diodes for the charge-pump stages — a standard practice that keeps the die small and the quiescent current low.
Supplied in an 8-VSSOP package (3.00 mm width, 0.118-inch pitch), the REG711EA-2.5/2K5 mounts on a standard surface-mount footprint. ROHS3 compliance is confirmed, so the part passes EU material restrictions without an exemption.
