XC6220Series
ETR0341-003
1A LDO Voltage Regulator with “GreenOperation”
☆GreenOperation-Compatible
■GENERAL DESCRIPTION
The XC6220 series is a highly accurate, low noise, high speed, low dropout, and large current CMOS voltage regulator with
GreenOperation function. The series consists of a voltage reference, an error amplifier, a current limiter, an inrush current
prevention circuit and a phase compensation circuit plus a driver transistor.
With a 0.2Ω on-resistance driver transistor integrated and with output currents up to 1A, the ultra low dropout voltage
performance greatly extends battery life as does the GreenOperation function which can switch between high speed and
power save modes automatically. Low ESR ceramic capacitors can be used for the output stabilization capacitor (CL).
Output voltage is selectable in 0.05V increments within the range of 0.8V~5.0V, using laser trimming technologies.
An over current protection circuit and a thermal shutdown circuit are built in. The over current protection circuit will operate
when the output current reaches its limit current. The thermal shutdown circuit will operate when the junction temperature
reaches its limit temperature. The inrush protection circuit works by controlling the inrush current which is charged to CL when
the IC starts up. In this way, any fluctuations to VIN caused by inrush current during system start up can be minimized.
The CE function enables the output to be turned off and the IC becomes a stand-by mode resulting in greatly reduced power
consumption.

* The No.5 and 6 VIN pins should be connected. The
No.1 and 2 pins VOUT pins should be connected. 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 (No. 4)

■OPERATIONAL EXPLANATION
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 the IC between two
operating modes according to the level of output
current. Further, the IC's internal circuitry can be
shutdown via the CE pin's signal.

<GreenOperation>
The XC6220 series can be set in a fixed high-speed mode or a green operation (GO) mode via a signal to the green operation
(GO) pin.
The GO mode enables the IC to switch automatically between the high speed (HS) mode or the power save (PS) mode
according to the level of output current. With the HS/PS automatic switching mode (GO mode), the switching point of the HS
mode and the PS mode is fixed inside the IC. When the output current becomes IGOR=1.0mA (MIN.) or below, the mode
changes automatically to the PS mode after a delay time of hundreds of microseconds. Supply current in light load is greatly
reduced. Also when the output current becomes IGO 10mA (MAX.) or more, the mode changes automatically to the HS
mode and the IC returns to high speed operation.
<Low ESR capacitor>
The XC6220 series has a built-in phase compensation circuit which means that a stable output voltage is achieved even if
the IC is used with low ESR capacitors. In order to ensure stable phase compensation it is recommended that a CL capacitor
is connected as close as possible to the VOUT pin and VSS pin. For a stable power supply, please connect an input capacitor
(CIN) between the VIN pin and the VSS pin.
Values required for the phase compensation are shown in the chart below. If a loss of the capacitance happens, the stable
phase compensation may not be obtained. Please ensure to use a capacitor which does not depend on bias or temperature
too much.

<Current Limiter, Short-Circuit Protection>
The XC6220 series includes a fold-back circuit, which aids the operation of the current limiter and circuit protection. When
the load current reaches the current limit level, the fold-back circuit operates and output voltage drops. As a result of this drop
in output voltage, output current also decreases. When the output pin is shorted, a current of about 180mA flows.
<CE Pin>
The IC's internal circuitry can be shutdown via the signal from the CE pin with the XC6220 series. With the XC6220B/D
series, output at the VOUT pin will be pulled down to the VSS level. However, with XC6220A/B 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, the time until the
VOUT pin reaches the VSS level is shortened. The output voltage becomes unstable, when the CE pin is open. If this IC is
used with the correct output voltage for the CE pin, the logic is fixed and the IC will operate normally. However, with the
XC6220C/D series, supply current may increase as a result of through current in the IC's internal circuitry when medium
voltage is input.

XC6220 Series
■OPERATIONAL EXPLANATION (Continued)
<CL High Speed Auto-Discharge Function>
The XC6220B/D series can quickly discharge the electric charge at the output capacitor (CL), when a low signal to the CE
pin, which enables the whole IC circuit put into an OFF state, is inputted to the CE pin via the N-channel transistor located
between the VOUT pin and the VSS pin (cf. BLOCK DIAGRAM). The CL auto-discharge resistance value is fixed to 460Ω
(VIN=6.0V, VOUT=5.0V at TYP.). The discharge time of the output capacitor (CL) is set by the CL auto-discharge resistance
(RDCHG) and the output capacitor (CL). By setting a time constant of the CL auto-discharge resistance value [RDCHG] and an
output capacitor value (CL) as τ(τ=C x RDCHG), the output voltage after discharge via the N channel transistor is calculated
by the following formulas.
V = VOUT x e –t/
,
or ｔ=τln（ VOUT(E) / V ）
τ
where
V : Output voltage after discharge
VOUT(E) : Output voltage
t: Discharge time
τ: CL auto-discharge resistance RDCHG×Output capacitor (CL) value C)
For the XC6220A/C series, output voltage may rises when in the high stand-by mode. Please note that in that case, the
typical characteristics may worse. When the XC6220A/C series is used, please be noted the characteristics shown below.

<Thermal Shutdown>
When the junction temperature of the built-in driver transistor reaches the temperature limit level (150℃ TYP.), the thermal
shutdown circuit operates and the driver transistor will be turned OFF. The IC resumes its operation when the thermal
shutdown function is released and the IC’s operation is automatically restored because the junction temperature drops to the
level of the thermal shutdown release voltage.
<Inrush Current Protection>
The XC6220 series includes an inrush current protection circuit.
The inrush current protection circuit suppresses inrush current charged to CL when the IC starts up to 700 mA (MAX.) for
approximately 1 ms.
* Please note that the device can not provide the an output current beyond 700 mA for a period of approximately 1 ms after
the CE pin goes high.
■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.
