the xc6604 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 XC6604 series is a low‑voltage input LDO regulator offering high accuracy (±15 mV/±20 mV) and up to 1 A output current. It includes protection circuits such as fold‑back current limit, thermal shutdown, UVLO, soft‑start and a CE pull‑down function for standby power reduction.
Key features include selectable output voltage in 0.1 V steps, ultra‑low on‑resistance (0.15 Ω), low quiescent current (100 µA), and RoHS‑compliant packaging (USP‑6C, SOT‑26W). The device is suited for mobile phones, cameras, tablets, e‑readers and wireless LAN applications.
| Maximum Output Current | 1 A (1.3 A limit) |
|---|---|
| Output Voltage Range | 0.5 V – 1.8 V (0.1 V steps) |
| Input Voltage Range | 0.5 V – 3.0 V |
| On‑Resistance | 0.15 Ω @ VBIAS=3.6 V, VOUT=1.2 V |
| Stand‑by Current | 0.01 µA (VBIAS), 0.01 µA (VIN) |

The current limit can be set by connecting a resistor to the I LIM pin, allowing up to a 1.3 A limit.
It includes a thermal shutdown circuit that disables the driver transistor at 150 °C and re‑enables it when the temperature falls below 125 °C.
