XC6902 Series ETR0363-003a -16V Input Three Terminal Negative Voltage Regulator GENERAL DESCRIPTION The XC6902 Series is a negative voltage CMOS regulator which includes a reference voltage source, error amplifiers, driver transistors, current limiters and phase compensators. XC6902 is a 3 terminal negative voltage regulator (without CE pin) which is capable of accepting -16V input. The over current protection circuit will operate when the output current reaches limit current. The thermal shutdown circuit will operate when the junction temperature reaches limit temperature. FEATURES APPLICATIONS Maximum Output Current : 200mA Negative power supplies Input Voltage Range : -2.4 -16V Output Voltage Range : -2.5V,-2.6V,-3.0V,-3.3V,-4.0V,-4.5V,-5.0V,-6.0V,-12.0V Modules (Wireless LAN, Digital still cameras, etc) Accuracy : 1.5% for -2.0V-12V Digital still cameras Temperature Stability : TYP. 50ppm/ Mobile devices / terminals Dropout Voltage : 400mVIOUT=100mA Low Power Consumption : 100A Protection Circuits : Current Limit 350mA TYP. Foldback Thermal Shutdown (150) Output Capacitor : Ceramic Capacitor Compatible : Operating Ambient -40~85 Temperature Packages : SOT-23, SOT-89, USP-6C Environmentally Friendly : EU RoHS Compliant, Pb Free TYPICAL PERFORMANCE TYPICAL APPLICATION CIRCUIT CHARACTERISTICS XC6902N501 GND I =1100mA,tr=tf=5s,Ta=25 OUT V =-6V,C =1F(ceramic),C =1F(ceramic) IN IN L -4.6 300 -VIN -4.8 250 Output Voltage CIN=1F -5.0 200 ceramic -VOUT -5.2 150 Output Current CIN=1F ceramic -5.4 100 1mA SOT-23 -5.6 50 100mA (TOP VIEW) -5.8 0 Time(100s/div) 1/23 Output Voltage: V V OUT Output Current: IOUT mA XC6902 Series PIN CONFIGURATION * The dissipation pad for the USP-6C package should be solder-plated in recommended mount pattern and metal masking to enhance mounting strength and heat release. If the pad needs to be connected to other pins, it should be connected to the -V (No. 3) pin.
