200mA Negative LDO Voltage Regulator
The new XC6901 series from Torex is a negative voltage regulator that is compatible with small ceramic capacitors. In addition to an output current capability of 200mA, the wide input (-2.4V ~ -12.4V) and output (-0.9V ~ -12V – available in 0.1V increments) voltage range of the XC6901 permits this IC to be used in most applications where negative DC to DC regulation is needed, such as CCD power supplies, LCD modules or digital cameras to name but a few.
The XC6901 series come with a high output voltage accuracy of ±1.5% for VOUT<-2.0V (±30mV when VOUT≥-2.0V), a low voltage dropout of 400mV @ 100mA, a high PSRR of 45dB @ 1kHz and a low current consumption of 100µA.
The XC6901 can be put into stand-by mode via the CE pin thereby reducing current consumption to only 0.1μA.
The XC6901 protection circuits consist of a foldback-type current limiter and a thermal shutdown circuit. In addition to these features, the XC6901 series also has a CL discharge function in order to swiftly return the output voltage to the VSS level when disabling the IC.
