XC6221 Series
ETR0328_014
■GENERAL DESCRIPTION
The XC6221 series is a high accuracy, low noise, high speed, low dropout CMOS regulator with high ripple rejection. The series
includes a reference voltage source, an error amplifier, a current limiter, and a phase compensation circuit.
The CE function enables the entire circuit to be in stand-by state by inputting low level signal. As for the XC6221B/D stand-by
mode, the electric charge at the output capacitor (CL) will be discharged by the internal auto-discharge switch, and as a result
the VOUT pin quickly returns to the VSS level. The output stabilization capacitor (CL) is also compatible with low ESR ceramic
capacitors.
Output voltage is selectable in 0.05V increments within a range of 0.80V~5.00V, using the laser trimming technology set in
factory.
The current limiter's fold-back circuit also operates as a short circuit protection and an output current limiter at the output pin.
The series achieves a fast response with only 25μA of low power consumption. Also the series has low dropout voltage
characteristics, which is 80mV at IOUT=100mA and VOUT=3.0V.
With the use of small USP-4 and ultra small USPN-4 packages, a small footprint circuit can be designed.

* 2: VOUT (E) = Effective output voltage
(The output voltage when an amply stabilized "VOUT (T) ＋1.0V" is provided at the VIN pin while maintaining a certain IOUT value.)
* 3: The relation between VOU T (E) and VOUT (T) is shown in the voltage chart E-0 and E-1.
* 4: VOUT (T) = Nominal output voltage
(*7)

* 5: Vdif = {VIN1 -VOUT1 }
* 6: VOUT1 is the voltage equal to 98% of the normal output voltage when amply stabilized VOUT (T) +1.0V are input at the VIN pin.
* 7: VIN1 is the input voltage when VOUT1 appears at the VOUT pin while input voltage is gradually decreased.
* 8: For the XC6221B/D series only. The XC6221A/C series discharges by resistors R1 and R2 only as shown in the block diagrams.
* 9: For operating supply current of the XC6221C/D, a current through the pull-down resistor should be considered in addition to the
supply current value mentioned above.

■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 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. Further, the IC's internal circuitry can be shutdown via the CE pin's signal.

<Input and Output Capacitors>
The XC6221 needs an output capacitor CL for phase compensation. 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. For a stable power input,
please connect an input capacitor CIN of 1.0μF between the VIN pin and the VSS pin.

<CL Auto-Discharge Function>
XC6221B/D series can discharge the electric charge in the output capacitor (CL), when a low signal to the CE pin, which
enables the whole IC circuit to be turned off, is inputted via the N-channel transistor and CL auto-discharge resistance
(RDCHG) located between the VOUT pin and the VSS pin (cf. BLOCK DIAGRAM). The CL auto-discharge resistance (RDCHG)
value is set at 780Ω(VOUT=4.0V @ VIN=6.0V at typical). The discharge time of the output capacitor (CL) is set by the CL
auto-discharge resistance (RDCHG) and the output capacitor (CL). By setting the time constant of the CL auto-discharge
resistance value [RDCHG] and the output capacitor value (CL) as τ(τ=CL x RDCHG), the output voltage after discharge via
the N-channel transistor is calculated by the following formula.
V = VOUT(E) x e –t/τ, or t=τIn ( V / VOUT(E) )
where
V : Output voltage after discharge
VOUT (E) : Output voltage
t : Discharge time
τ: CL auto-discharge resistance RDCHG×Output capacitor value CL

■OPERATIONAL EXPLANATION (Continued)
<Current Limiter, Short-Circuit Protection>
The XC6221 series’ fold-back circuit operates as an output current limiter and a short protection circuit for the output pin.
When the load current reaches the current limit level, the fixed current limiter circuit operates and output voltage drops.
When the output pin is short-circuited to the VSS pin, the current falls and reaches about 30mA.
<CE Pin>
The XC6221 internal circuitry can be shutdown via the CE pin signal. In shutdown mode, output at the VOUT pin will be
pulled down to the VSS level via R1 & R2. However, with the XC6221B/D 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 is shorter. For the XC6221A/B, the output voltage becomes unstable, when the CE pin is left
open. For the XC6221C/D, the output voltage becomes VSS level because the CE pin is short-circuited to VSS via an
internal pull-down resistor. However, the CE input current will be increased via a pull-down resistor when the IC
operates. 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, the supply current may increase as a result of shoot-through current in the IC's internal circuitry
when a medium voltage is input.
■NOTES ON USE
1. Please use this IC within the stated maximum ratings. For temporary, transitional voltage drop or voltage rising
phenomenon, 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 wire the input capacitor (CIN) and the output capacitor (CL) as close to the IC as possible.
3. Torex places an importance on improving our products and its reliability.
However, by any possibility, we would request user fail-safe design and post-aging treatment on system or equipment.
