■GENERAL
DESCRIPTION
The XC6207 series are precise, low noise, high speed, 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 50mV increments within a range
of 1.2V~5.0V, using laser trimming technologies.
The series' output stabilization capacitor (CL) 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 VOUT and VSS pins. This short enables the
electric charge at the output capacitor (CL) to be discharged
via the internal auto-discharge resistance, and as a result the
VOUT pin quickly returns to the VSS 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 VSS pin, No. 5.
