Dual High Speed LDO Regulator (ch1: 300mA, ch2: 100mA) with ON/OFF Control
The XC6419 series is a dual CMOS LDO regulator. The series features high accuracy, low output noise, high ripple rejection and low dropout and consists of a voltage reference, error amplifier, driver transistor, current limiter, thermal shutdown circuit and phase compensation circuit. Each output voltage is set independently by laser trimming and selectable in 0.05V increments within a range of 0.8 to 5.0V.
The EN function turns each output of the two regulators off 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. The high level of output stability is maintained even during frequent load fluctuations, due to the excellent transient response performance. VR1 and VR2 are completely isolated so that a cross talk during load fluctuations is minimized.

What is the standby current?
The current that flows through the IC in the standby mode. The standby mode means the state where the IC has been turned off by the CE function.
