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

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. www.SiliconStandard.com 3 of 7 SS6721G/DG TYPICAL PERFORMANCE CHARACTERISTICS 60 50 103 Ground Current (µA) Normalized Output Voltage (%) 104 100 98 40 30 20 10 96 0 -40 0 0 50 100 125 0 2 4 Fig. 1 Output Voltage vs. Temperature Fig. 2 60 Dropout Voltage (mV) Ground Current (µA) 10 Ground Current vs. Input Voltage VOUT=3.3V 500 IL =300mA 56 IL =150mA 54 IL=0.1mA 52 400 300 200 VOUT=5.0V 100 -50 -25 0 25 50 75 100 0 125 0 Temperature (°C) Fig. 3 Ground Current vs. Temperature 500 100 Fig. 4 150 25 0 2 00 300 Dropout Voltage vs. Load Current 500 VOUT=5V IL=300mA SS6721D 400 Short Circuit Current (mA) 400 IL=150mA 300 200 300 100 IL=0.1mA 0 -50 50 Load Current (mA) 600 Dropout Voltage(mV) 8 600 58 50 6 Input Voltage (V) Temperature (°C) -25 0 25 50 75 100 Temperature(°C) Fig. 5 Dropout Voltage vs Temperature 1/21/2005 Rev.2.01 125 200 SS6721 -50 -25 0 25 50 75 100 125 Temperature (°C) Fig. 6 www.SiliconStandard.com Short Circuit Current vs. Temperature 4 of 7 SS6721G/DG TYPICAL PERFORMANCE CHARACTERISTICS (Continued) Output Voltage (mV, AC) 100 50 0 COUT=1µF IL=1mA VOUT=5V Load Current (mA) -50 Input Voltage (V) Output Voltage (mV, AC) 100 8 6 0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 0 -100 COUT=1µF -200 VOUT=5V 150 0.1 1.0 0 Time (mS) 0.5 Fig. 7 Line Transient Response 1.0 1.5 Fig. 8 2.0 2.5 3.0 Time (mS) 3.5 4.0 4.5 5.0 Load Transient Response COUT=10µF Output Voltage (mA, AC) 20 VOUT=5V 0 -20 Load Current (mA) -40 -60 150 0.1 0 0.5 1.0 1.5 Fig. 9 2.0 2.5 3.0 3.5 4.0 4.5 5.0 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.
