SS6721G

SS6721G/DG 150mA/300mA Low Dropout Linear Regulator with 1% Output Accuracy FEATURES Low dropout voltage of 130mV at 100mA output current (5V output version). Guaranteed 150mA/300mA output current. Internal 1.3Ω P-MOSFET draws no base-current. Low ground current of 55µA. Output voltage accuracy of 1% at 3.3V/5V. Input voltage range up to 12V (5V output version) Extremely tight load and line regulation. Fast transient response. Current limiting and thermal protection. DESCRIPTION The SS6721/6721D are 150/300mA low dropout linear regulators. The superior characteristics of the SS6721 and SS6721D include zero base-current loss, very low dropout voltage, and 1% accuracy o f o utput voltage. Typical ground current i s a pproximately 5 5 µ A, across the load r ange from zero to maximum. With an output current of 100mA, the dropout voltage of the SS6721 and SS6721D is substantially lower (130mV for SS6721-50 and SS6721D-50, and 180mV for the SS6721-33 and SS6721D-33) when compared with a bipolar device. Built-in output current and thermal limiting provide maximum protection of the SS6721 and SS6721D against fault conditions. The SS6721 and SS6721D are available in the popular SOT-89 and TO-92 packages. RoHS compliant. APPLICATIONS LAN Cards. Wireless Communication Systems. Battery Powered Systems.

Regulation is measured at a constant junction temperature, which is maintained using pulse testing. Current limit is measured by pulse testing. Dropout voltage is defined as voltage differential at which the output voltage drops 100mV with an initial 1V differential between input and output. Specifications over -40°C to 85°C operating temperature range are guaranteed by design with Statistical Quality Controls (SQC), not production test. 1/21/2005 Rev.2.01 www.SiliconStandard.com 3 of 7 SS6721G/DG TYPICAL PERFORMANCE CHARACTERISTICS 104 60 Normalized Output Voltage (%) 50 Ground Current (µA) -40 0 0 50 1 00 12 5 103 40 100 30 20 98 10 96 0 0 2 4 6 8 10 Temperature (°C) Fig. 1 Output Voltage vs. Temperature Fig. 2 Input Voltage (V) Ground Current vs. Input Voltage 60 6 00 58 5 00 VOUT=3.3V Ground Current (µA) Dropout Voltage (mV) 56 IL =300mA IL =150mA 4 00 3 00 54 2 00 52 IL=0.1mA VOUT=5.0V 1 00 50 -50 -25 0 25 50 75 100 125 0 0 50 1 00 150 2 00 25 0 300 Temperature (°C) Fig. 3 Ground Current vs. Temperature 600 500 Load Current (mA) Fig. 4 Dropout Voltage vs. Load Current 500 VOUT=5V IL=300mA SS6721D Short Circuit Current (mA) 400 Dropout Voltage(mV) 400 300 IL=150mA 200 300 100 SS6721 IL=0.1mA 0 -50 -25 0 25 50 75 100 1 25 200 -50 -25 0 25 50 75 100 125 Temperature(°C) Fig. 5 Dropout Voltage vs Temperature Temperature (°C) Fig. 6 Short Circuit Current vs. Temperature 1/21/2005 Rev.2.01 www.SiliconStandard.com 4 of 7 SS6721G/DG TYPICAL PERFORMANCE CHARACTERISTICS (Continued) 100 Output Voltage (mV, AC) 50 0 -50 Output Voltage (mV, AC) 100 0 COUT=1µF IL=1mA VOUT=5V -100 -200 COUT=1µF VOUT=5V Load Current (mA) 0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1.0 Input Voltage (V) 8 6 150 0.1 Time (mS) Fig. 7 Line Transient Response 0 0.5 1.0 1.5 2.0 Time (mS) 2.5 3.0 3.5 4.0 4.5 5.0 Fig. 8 Load Transient Response COUT=10µF Output Voltage (mA, AC) 20 0 VOUT=5V -20 -40 -60 Load Current (mA) 150 0.1 0 0.5 1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5 5.0 Fig. 9 Time (mS) Load Transient Response BLOCK DIAGRAM VIN VOUT CURRENT LIMITING ERROR AMP THERMAL LIMITING + - + VREF 1.235V GND 1/21/2005 Rev.2.01 www.SiliconStandard.com 5 of 7 SS6721G/DG PIN DESCRIPTIONS VOUT PIN - Output pin.
