■GENERAL DESCRIPTION

■FEATURES

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.

Output Current

Dropout Voltage

: 200mA <Up to 250mA (TYP.)>

: 80mV@ IOUT=100mA,

VOUT(T)=3.0V

Operating Voltage Range : 1.6V ~ 6.0V (0.8V≦VOUT(T)≦1.55V

: 1.8V ~ 6.0V (1.6V≦VOUT(T)≦4.0V

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.

Output Voltage

Setting Range

Accuracy

: 0.8V~4.0V (50mV increments)

: +2% (HS: VOUT >2.0V)

+30mV (HS: VOUT≦1.95V)

+2.5%, -3.5% (PS: VOUT >2.6V)

+3.5%, -4.5% (PS:1.6≦VOUT≦2.55V)

+70mV, -90mV (PS:0.8≦VOUT≦1.55V)

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.

Low Power Consumption: 4.5μA (TYP.) when PS mode

25μA (TYP.) when HS mode

Standby Current

: Less than 0.1μA

High Ripple Rejection

: 70dB @ 1kHz (When HS mode)

Operating Temperature : -40℃~85℃

Range

Low ESR Capacitor

Ultra Small Packages

: 1.0μF Ceramic capacitor

Output voltage is selectable in 50mV increments within a range

of 0.8V~4.0V, using laser trimming technologies.

compatible

: USP-4D, SOT-25,

The current limiter's foldback circuit also operates as a short

circuit protection for the output current limiter and the output

pin.

■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 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.

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.

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.

SETTING OUTPUT VOLTAGE (V)

More than CL=4.7uF

0.8 ~ 1.15

1.2 ~ 1.35

1.4 ~ 4.0

More than CL=2.2uF

More than CL=1.0uF

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 [Rdischg] and an output capacitor value

(CL) as τ(τ=C x Rdischg), the output voltage after discharge via the N channel transistor is calculated by the following

formulas.

V = VOUT(E) x e ^–t/

,

or t=τIn ( V / VOUT(E) )

τ

( V : Output voltage after discharge, VOUT(E) : Output voltage, t: Discharge time,

τ: CL auto-discharge resistance Rdischg×Output capacitor (CL) value C)

■OPERATIONAL EXPLANATION (Continued)

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.

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.
