XC6416
Series
Dual LDO Voltage Regulator with “GreenOperation”
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 (C
L
) is discharged via the internal auto-discharge switch, and as a result the V
OUT
voltage quickly returns to the V
SS
level. The output stabilization capacitor (C
L
) 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 current limiter and circuit protection.
