| Impala Linear Corporation ILC7070 SOT-23 CMOS LDO Regulator with Shutdown General Description 150mA CMOS LDO regulator in a 5-lead SOT-23 package, featuring 120mV dropout at 100mA levels and nearly negligible dropout below 5mA. The part offers 2% precision as standard, yet draws only 5A of current in operation and drops to 0.5A in shutdown. The outputs offer short-circuit protection, and the shutdown pin has an internal pull-down which will disable the output if the pin is left floating. * * * * * * * Features All-CMOS design in 5-lead SOT-23 package 2% precision outputs Up to 150mA output current 120mV dropout at 100mA load Only 5A quiescent current at full load 0.5A quiescent current in shutdown Voltage options allow: 50mA 5V Regulator 50mA 5V to 3.3, 3.0, or 2.5V Convertor 150mA 3.3V or 3.0V to 2.5V Convertor Applications * * * * Battery-powered Equipment Reference voltage sources Portable Cameras and Video Recorders PDAs Ordering Information ILC7070HCM-25 ILC7070HCM-30 ILC7070HCM-33 ICL7070HCM-50 50mA 5V to 2.5V regulator, or 150mA 3.x to 2.5V regulator, High-level true Chip Enable 50mA 5V to 3.0V regulator, High-level true Chip Enable 50mA 5V to 3.3V regulator, High-level true Chip Enable 30mA 5V regulator, High-level true Chip Enable Block Diagram VIN SHORT-CIRCUIT PROTECT SHUTDOWN CONTROL REFERENCE VOLTAGE SOURCE Pin-Package Configurations VOUT VOUT 5 VSS 4 + VSS SOT-23-5 (TOP VIEW) 1 (NC) 2 VIN 3 CE CE Impala Linear Corporation ILC7070 1.1 (408) 574-3939 www.impalalinear.com Oct 1999 1 SOT-23 CMOS LDO Regulator with Shutdown Absolute Maximum Ratings (TA = 25C) Parameter Input Voltage CE Input Voltage Output Current Output Voltage Continuous Total Power Dissipation Operating Ambient Temperature Storage Temperature Symbol VIN VCE IOUT VOUT Pd(max) Topr Tstg Ratings 12 VSS-.0.3~VIN + 0.3 500 VSS-0.3~VIN + 0.3 150 -30~+80 -40~+125 Units V V mA V mW C C Note: IOUT must be less than Pd(max) / (VIN-VOUT) Electrical Characteristics ILC7070HCM-50 VOUT = 5.0V, TA =25C Parameter Output Voltage Maximum Output Current Load Stability Input/Output Voltage Differential Supply Current 1 Supply Current 2 Input Stability ISS1 ISS2 VOUT VIN * VOUT Input Voltage Output Voltage Temperature Characteristics CE Input Current CE ON Voltage CE OFF Voltage VIN VOUT Topr * VOUT IIH IIL CE(ON) CI(OFF) IOUT = 40mA -30C < Topr < 80C VIN = 6.0V, VCE = 2.5V VIN = 6.0V, VCE = 0 VIN = 6.0V VIN = 6.0V 2.5 0 2 4 0.1 VIN 0.7 V V 100 VIN = VCE = 6.0V VIN = 6.0V, VCE = open (Note 5) IOUT = 40mA 6.0V < VIN < 10.0V 10 V ppm/ C A 6 0.5 12 2.0 0.3 A A %/V Symbol VOUT IOUTmax VOUT Vdif Conditions IOUT = 40mA, VIN = 6.0V VIN = 6.0V, VOUT > 4.5V VIN = 6.0V, 1mA < IOUT < 100mA IOUT = 100mA, VOUT = VSET x 0.98 200 Min 4.90 125 80 300 Typ 5.0 Max 5.10 Units V mA mV mV Impala Linear Corporation ILC7070 1.1 (408) 574-3939 www.impalalinear.com Oct 1999 2 SOT-23 CMOS LDO Regulator with Shutdown Electrical Characteristics ILC7070HCM-25 VOUT = 2.5V, TA = 25C Parameter Output Voltage Maximum Output Current Load Stability Input/Output Voltage Differential Supply Current 1 Supply Current 2 Input Stability Input Voltage Output Voltage Temperature Characteristics CE Input Current CE ON Voltage CE OFF Voltage ISS1 ISS2 VOUT VIN * VOUT VIN VOUT Topr * VOUT IIH IIL CE(ON) CE(OFF) IOUT = 40mA -30C < Topr < 80C VIN = 3.5V, VCE = 3.5V VIN = 3.5V, VCE = 0V VIN = 3.5V VIN = 3.5V 2.5 0 2 4 0.1 VIN 0.7 V V A 100 VIN = VCE = 3.5V VIN = 3.5V, VCE = open (Note 5) IOUT = 40mA 3.5V< VIN < 10V 10.0 V ppm/C 5 0.5 0.2 10 2 0.3 A A %/V Symbol VOUT IOUTmax VOUT Vdif Conditions IOUT = 40mA, VIN = 3.5V VIN = 3.5V, VOUT > 2.25V VIN = 3.5V, 1mA < IOUT < 60mA IOUT = 60mA, VOUT = VSET x .98 Min 2.450 125 45 180 90 360 Typ 2.5 Max 2.55 Units V mA mV mV Note: 1. VOUT means the output voltage when "VOUT + 1.0V" is provided at the VIN pin while maintaining a certain IOUT value. 2. VIN1 is defined as the input value that is gradually decreased until the output value reaches VOUT x 98%. 3. Vdif is defined as "VIN1-VOUT." 4. IOUT: this is limited by continuous total power dissipation in the package. 5. When VCE is LOW or OPEN, the output is disabled. Note: CE pin is a CMOS input. Because of this, when the input voltage reaches VIN/2, a rush current will start to flow.
