XC6217 Series
ETR0322_013a
High Speed "Green Operation" LDO Voltage Regulators
☆GreenOperation Compatible
■GENERAL DESCRIPTION
The XC6217 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.
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. 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
XC6217B/D 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 series' 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~4.00V, using laser trimming technologies.
The current limiter's foldback circuit also operates as a short circuit protection for the output current limiter and the output pin.

XC6217 Series
■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>
XC6217A and B 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 GO pin becomes low level, the IC operates in the GO mode and the IC
operates in the fixed high-speed mode when the GO pin is at high 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 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 0.5mA (MIN.) or below, the mode changes automatically to the PS mode after the
delay time of hundreds μsec(s), and it can reduce supply current in light load. Also when the output current becomes IGO
8mA (MAX.) or more, the mode changes automatically to the HS mode and the IC becomes high speed operation.
When the XC6217 is used in the GO mode, stable operation range is over 8.0mA is HS mode and below 0.5mA in PS mode.
<Low ESR capacitor>
With the XC6217 series, a stable output voltage is achievable even if used with low ESR capacitors, as a phase
compensation circuit is built-in. Values required for the phase compensation are as the chart below. In order to ensure the
stable phase compensation while avoiding run-out of values, please use the 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.

XC6217
Series
<CL Auto-Discharge Function>
XC6217B/D 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). The CL auto-discharge resistance value is fixed to 780Ω(VIN=6.0V, VOUT=4.0V at
typical). The 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 [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(E) x e –t/τ, or t=τIn ( V / VOUT(E) )
( V : Output voltage after discharge, VOUT(E) : Output voltage, t: Discharge time,
τ: CL auto-discharge resistance RDCHG×Output capacitor (CL) value C)
<Current Limiter, Short-Circuit Protection>
The XC6217 series’ foldback circuit operates as an output current limiter and a short protection of the output pin. 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, output voltage drops further and output current
decreases. When the output pin is shorted to the VSS level, a current of about 30mA flows.
<CE Pin>
The IC's internal circuitry can be shutdown via the signal from the CE pin with the XC6217 series. In shutdown mode,
output at the VOUT pin will be pulled down to the VSS level via R1 & R2. However, as for the XC6217B/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 becomes short. 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, 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.
