■GENERAL DESCRIPTION

■FEATURES

The XC6207 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 voltage is selectable in 50mV 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

: Less than 0.1μA

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.

: Ceramic capacitor compatible

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.

SOT-25

USP-6C

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.

*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 pin, No. 5.

XC6207

Series

■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.

Reference

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 fixed high-speed mode

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 µsec(s), 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,

and control the supply current according to the system condition. Furthermore, the high-speed operation might be

required. In such a case, at the automatic switching mode (GO mode), when the output current becomes IGO or more,

the mode will automatically switch to the HS mode. 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 µsec(s), the output voltage drops more than in the fixed HS mode. If the GO pin voltage is at high level {tens

of µsec(s) 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 you use the

IC 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.

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.

■OPERATIONAL EXPLANATION (Continued)

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/

XC6207 Series

■OPERATIONAL EXPLANATION (Continued)

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, output

voltage drops further and output current decreases. When the output pin is shorted, a current of about 50mA flows.

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. Although the CE pin is equal to an inverter input

with CMOS hysteresis, with either the pull-up or pull-down options, the CE pin input current will increase when the IC is in

operation. 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.
