XC6416

XC6416 Series Dual LDO Voltage Regulator with “GreenOperation” www.DataSheet4U.com JTR0333-006 GENERAL DESCRIPTION GreenOperation Compatible The XC6416 series is a high accurate, low noise, high ripple rejection, and low dropout CMOS Dual regulator with GreenOperation function. The series includes a reference voltage source, an error amplifier, a current limiter, and a phase compensation circuit. GreenOperation function provides high speed operation, low power consumption and high efficiencies by automatically switching between a high speed mode (HS) and a power save mode (PS) depending on the load current level. The switching point of the GreenOperation to the output current is being fixed inside the IC, thus providing operating conditions with the most suitable level of supply current for the application. The USP-6C package has GO pin. If a high level singal is input to the GO pin, the XC6416 can be used as a high speed fixed mode regulator. The EN function turns each output of the two regulators independently. In this state, the electric charge at the output capacitor (CL) is discharged via the internal auto-discharge switch, and as a result the VOUT voltage quickly returns to the VSS level. The output stabilization capacitor (CL) is also compatible with low ESR ceramic capacitors. Output voltage is selectable in 0.05V increments within a range of 0.8V ~4.0V, using laser trimming technologies. The series includes a fold-back circuit, which aids the operation of the cur...
