1 / 30 page 1/30 XC6220 Series 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 and with output currents up to 1A, the ultra low dropout voltage performance greatly extends battery life as does the GreenOperation function which can switch between high speed and power save modes automatically. Low ESR ceramic capacitors can be used for the output stabilization capacitor (CL). 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 protection circuit works by controlling the inrush current which is charged to CL when the IC starts up. In this way, any fluctuations to VIN 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. ■ APPLICATIONS ● CD-ROM, CD-R/RW drives ● DVD drives ● HDD drives ● MIDs, UMPCs ● Digital still cameras, Video cameras ● Portable AV equipment ■ TYPICAL APPLICATION CIRCUIT ETR0341-007 ■ FEATURES Maximum Output Current Dropout Voltage Operating Voltage Range Output Voltage Range Accuracy Low Power Consumption Operating Temperature Thermal Shutdown Inrush Current Protection CL Auto Discharge CE Pull-Down Resistor Output Capacitor Packages Environmentally Friendly : 1000mA (TYP.:1200mA limit) (1.2V≦VOUT≦5.0V) : 20mV @ 100mA (VOUT=3.0V) : 60mV@ 300mA (VOUT=3.0V) : 1.6V ~ 6.0V : 0.8V ~ 5.0V (0.05V increments) :±1% (VOUT≧2.0V) :±20mV (VOUT<2.0V) : 8μA (TYP.) in PS mode : 50μA (TYP.) in HS mode : - 40℃~ +85℃ : Detect 150℃, Release 135℃(TYP.) : 700mA (MAX.) : XC6220B/D Series : XC6220C/D Series : Ceramic Capacitor Compatible : USP-6C, SOT-25, SOT-89-5 : EU RoHS Compliant, Pb Free ■ TYPICAL PERFORMANCE CHARACTERISTICS XC6220x 181 0 100 200 300 400 500 0 200 400 600 800 1000 Output Current: IOUT (mA) Topr=25℃ Topr=-40℃ Topr=85℃ CE=V IN, CIN=CL=10μF (ceramic) |
