ETR0316_005
The XC6207 series are precise, low noise, high speed, and low dropout regulators with green operation (GO) function. They are
fabricated using Torex’s CMOS process. Performance features of the series include high ripple rejection and low dropout
voltage, and the series include a reference voltage source, an error amplifier, a current limiter, and a phase compensation
circuit. Output voltage is selectable in 0.05V increments within a range of 1.2V~5.0V, using laser trimming technologies. The
series' output stabilization capacitor (C
L
) is also compatible with low ESR ceramic capacitors. GO 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 upon the load current level. The switching point of the GO to the output current is being
fixed inside the IC. The IC operates when the GO pin is low-level. When only high-speed operation is required, it can be fixed
by inputting a high level signal to the GO pin, thus providing operating conditions with the most suitable level of supply current
for the application. The CE function enables the output to be turned off resulting in greatly reduced power consumption. In
this state, with the XC6207B series, the IC turns on the internal switch located between the V
OUT
and V
SS
pins. This short
enables the electric charge at the output capacitor (C
L
) to be discharged via the internal auto-discharge resistance, and as a
result the V
OUT
pin quickly returns to the V
SS
level. The constant current limit circuit and the current limiter's foldback circuit
also operate as a short circuit protection for the output current limiter and the output pin.

*The dissipation pad for the USP-6C package
should be solder-plated in recommended mount
pattern and metal masking so as to enhance
mounting strength and heat release.
If the pad needs to be connected to other pins, it
should be connected to the V
