The XC6603 series is a low voltage input (0.5V) operation and provides high accuracy ±15mV / ±20mV and can supply large current efficiently due to its ultra low on-resistance even at low output voltages.
The XC6603 series is a low‑input (0.5 V) LDO regulator offering high accuracy (±15 mV/±20 mV) and up to 1 A continuous output current with an ultra‑low on‑resistance. It includes built‑in protection functions such as foldback current limit, thermal shutdown, UVLO, soft‑start and CE pull‑down for standby operation.
Typical applications include mobile phones, digital cameras, tablets, e‑book readers and wireless LAN devices. The device is offered in USP‑6C and SOT‑26W packages and complies with RoHS and Pb‑free requirements.
