The XC6601 series low voltage input CMOS LDO regulator provides highly accurate (±20mV) outputs and can supply current efficiently due to its ultra low on-resistance even at low output voltages. The series is ideally suited to the applications which require very low dropout voltage operation and consists of a voltage reference, an error amplifier, linear regulator and output buffer.
The XC6601 series provides a low‑voltage input LDO solution for mobile phones, wireless equipment, portable games, cameras, AV gear and PDAs. It features selectable output voltage in 0.05 V steps, built‑in UVLO, soft‑start, auto‑discharge and over‑current protection.
Key specifications include a 400 mA typical output current (550 mA limit), 38 mV dropout at 100 mA, 0.7‑1.8 V output range, 1.0‑3.0 V input range, and operation from –40 °C to +85 °C. The device is supplied in USP‑6C, SOT‑25 and SOT‑89‑5 packages and complies with RoHS.
