XC6220 Series

ETR0341-010a

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, the ultra low dropout voltage performance with output currents up to 1A greatly extends battery life as does the GreenOperation function which can switch between high speed and power save modes automatically. A low ESR ceramic capacitor can be used for the output stabilization capacitor (C 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 prevention circuit works by controlling the inrush current which charges to C the IC starts up. In this way, voltage fluctuations in power supply 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.

<GreenOperation> The XC6220 series always operates in a green operation (GO) mode. 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. The switching point of the HS mode and the PS mode is

fixed inside the IC. When the output current becomes I

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 I

more, the mode changes automatically to the HS mode and the IC

returns to high speed operation.

GOR

10mA (MAX.) or

GO

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 C is connected as close as possible to the V (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.

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 XC6220A/C series, output at the V N-channel transistor switch is connected in parallel to R1 and R2 while the power supply is applied to the V the time until the V 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. On the other hand, with the XC6220C/D series, the IC operation is stopped when the CE pin is open. However, the CE pin input current may increase as a result of through current in the pull-down resistor (R IC is under operation.

■NOTES ON USE

1. 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 strengthen V
