200mA Negative LDO Voltage Regulator
The XC6901D501MR-G 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 XC6901D501MR-G 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 XC6901D501MR-G 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 XC6901D501MR-G can be put into stand-by mode via the CE pin thereby reducing current consumption to only 0.1μA.
The XC6901D501MR-G protection circuits consist of a foldback-type current limiter and a thermal shutdown circuit. In addition to these features, the XC6901D501MR-G series also has a CL discharge function in order to swiftly return the output voltage to the VSS level when disabling the IC.
