The XC6901 Series is a negative voltage CMOS regulator which includes a reference voltage source, error amplifier, driver transistor, current limiter and phase compensator. It can be applied to CCD power supplies, LCD modules, op-amp power supplies, digital still cameras, battery powered equipment, etc.
The XC6901 Series is a negative‑voltage CMOS regulator offering up to 200 mA output current and selectable output voltages from –0.9 V to –12 V. It includes a reference source, error amplifier, driver transistor, current‑limit and phase‑compensation circuits, and an optional CE pin for standby control.
The device is supplied in SOT‑25, SOT‑89‑5 and USP‑6C packages, supports a wide input range (‑2.4 V to ‑12.4 V), and features over‑current protection, fold‑back, and thermal shutdown for reliable operation in CCD power supplies, LCD modules, and battery‑powered equipment.
| Maximum Output Current | 200 mA |
|---|---|
| Input Voltage Range | -2.4 V to -12.4 V |
| Output Voltage Range | -0.9 V to -12.0 V |
| Accuracy (VOUT < -2.0 V) | ±1.5 % |
| Dropout Voltage (IOUT=100 mA) | 400 mV |
| Stand‑by Current | < 0.1 µA |
| Operating Ambient Temperature | -40 °C to +85 °C |
| Available Packages | SOT‑25, SOT‑89‑5, USP‑6C |
The CE pin enables standby mode when a low‑level signal is applied and controls the ON/OFF function of the regulator.
During standby, the internal auto‑discharge switch discharges the output capacitor, causing the –VOUT pin to quickly return to the VSS (ground) level.
It is available in SOT‑25, SOT‑89‑5, and USP‑6C surface‑mount packages.
