■GENERAL DESCRIPTION
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 (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.

■OPERATIONAL EXPLANATION
<Output Voltage Control>
The voltage divided by resistors R1 & R2 is compared with the internal reference voltage by the error amplifier. The
P-channel MOSFET, which is connected to the VOUT pin, is then driven by the subsequent output signal. The output
voltage at the VOUT pin is controlled & stabilized by a system of negative feedback. The current limit circuit and short
protect circuit operate in relation to the level of output current. The GO function monitors the output current and switches
a supply current to two values according to the level of output current. Further, the IC's internal circuitry can be shutdown
via the CE pin's signal.
<Green Operation>
XC6207 series can be set as a fixed high-speed mode or a green operation (GO) mode via a signal to the green operation
(GO) pin. Under the condition that the output current becomes IGOR or less, the IC operates in the high speed mode (HS)
when the GO pin is at high level and the IC operates in the power save (PS) mode when the GO pin is at low level. The
GO mode enables the IC to switch automatically the supply current to the high speed (HS) mode or the power save (PS)
mode according to the level of output current. While having both high-speed operation and low supply current state, the
XC6207 series can acquire high efficiency. At the HS/PS automatic switching mode (GO mode), the switching point of
the HS mode and the PS mode is being fixed inside the IC. When the output current becomes IGOR 0.3mA (TYP.) or
below, the mode changes automatically to the PS mode after the delay time of hundreds μs, and it can reduce supply
current in light load. For applications, most of portable equipment control the system current, which is the output current
to the IC, according to the system condition. Furthermore, the high-speed operation might be required. In such a case,
the mode will automatically switch to the HS mode at the automatic switching mode (GO mode), when the output current
becomes IGO or more. In the HS mode, the response of the output voltage during the output current fluctuation is better
than the PS mode. Automatic switching PS mode to HS mode causes the switching delay time of tens of μs, the output
voltage drops more than in the fixed HS mode. If the GO pin voltage is at high level (tens of μs (ΔT) before the output
current fluctuation occurs) and the IC is used in the HS mode, the output current fluctuation will be suppressed to as low as
the fixed HS mode. (cf. the following item: Load Transient Response by Switching Mode with GO pin.)
The output current at the HS/PS mode should be adjusted to 2.0mA or more / 0.3mA or less respectively when the IC is
used in the HS/PS automatic switching mode (GO mode).
It is suggested that you use this IC with either a VIN voltage or a VSS voltage input at the GO pin. If this IC is used with the
correct specifications for the GO pin, the IC will operate normally. However, supply current may increase as a result of
through current in the IC's internal circuitry when medium voltage is input.

<Low ESR capacitor>
With the XC6207 series, a stable output voltage is achievable even if used with low ESR capacitors, as a phase
compensation circuit is built-in. In order to ensure the effectiveness of the phase compensation, we suggest that an
output capacitor (CL) is connected as close as possible to the output pin (VOUT) and the VSS pin. Please use an output
capacitor with a capacitance value of at least 1μF when the setting output voltage (VOUT(T)) is less than or equal to 1.8V.
Also, when the setting output voltage (VOUT(T)) is less than or equal to 2.5V, please connect an input capacitor (CIN) of
2.2μF between the VIN pin and the VSS pin in order to ensure a stable power input. The capacitor is possible to
decrease depends on bias and temperature. Therefore the phase compensation cannot be ensured effectiveness.
Stable phase compensation may not be ensured if the capacitor runs out capacitance when depending on bias and
temperature. In case the capacitor depends on the bias and temperature, please make sure the capacitor can ensure
the actual capacitance.

■OPERATIONAL EXPLANATION (Continued)
<CL Auto-Discharge Function>
XC6207B series can quickly discharge the electric charge at the output capacitor (CL), when a low signal to the CE pin,
which enables a whole IC circuit put into OFF state, is inputted via the N-channel transistor located between the VOUT pin
and the VSS pin (cf. BLOCK DIAGRAM). In this state, the application is protected from a glitch operation caused by the
electric charge at the output capacitor (CL). The CL auto- discharge resistance at this time depends on the input
voltage. Moreover, discharge time of the output capacitor (CL) is set by the CL auto-discharge resistance (R) and the
output capacitor (CL). By setting time constant of a CL auto-discharge resistance value [R] and an output capacitor value
(CL) as τ(τ=C x R), the output voltage after discharge via the N channel transistor is calculated by the following
formulas.
V = VOUT x e –t/
,
or t=τIn (VOUT / V)

■OPERATIONAL EXPLANATION (Continued)
<Current Limiter, Short-Circuit Protection>
The XC6207 series includes a combination of a fixed current limiter circuit & a foldback circuit, which aid the operations
of the current limiter and circuit protection. When the load current reaches the current limit level, the fixed current limiter
circuit operates and output voltage drops. As a result of this drop in output voltage, the foldback circuit operates and
output voltage drops further and output current decreases. When the output pin is shorted, a current of about 50mA
flows.
<The CE Pin>
The IC's internal circuitry can be shutdown via the signal from the CE pin with the XC6207 series. In shutdown mode,
output at the VOUT pin will be pulled down to the VSS level via R1 & R2. However, as for the XC6207B series, the CL
auto-discharge resistor is connected in parallel to R1 and R2 while the power supply is applied to the VIN pin.
Therefore, time until the VOUT pin reaches the VSS level becomes short. We suggest that you use this IC with either a
VIN voltage or a VSS voltage input at the CE pin. If this IC is used with the correct specifications for the CE pin, the IC will
operate normally. However, supply current may increase as a result of through current in the IC's internal circuitry when
medium voltage is input.
■NOTES ON USE
1. Please use this IC within the stated absolute maximum ratings. The IC is liable to malfunction should the ratings be
exceeded.
2. Where wiring impedance is high, operations may become unstable due to noise and/or phase lag depending on output
current. Please strengthen VIN and VSS wiring in particular.
3. Please wire the input capacitor (CIN) and the output capacitor (CL) as close to the IC as possible.
