SS6732 300mA Low Dropout Linear Regulator n FEATURES l l l n DESCRIPTION Thve SS6732 is a 3-pin low-dropout linear regulator. The superior characteristics of the SS6732 include zero base current loss, very low dropout voltage, and 2% accurate output voltage. Typical ground current remains approximately 55µA, under output l l l l l Low dropout voltage of 130mV at 100mA output current (5.2V output version). Guaranteed 300mA output current. Internal 1.3Ω P-MOSFET draws no base current. Low ground current: 55uA. Accuracy of output voltage 2% of 3.3V/ 3.4V/ 3.5V/ 3.6V/ 3.7V/ 3.8V/ 5.0V/ 5.2V. Input voltage range up to 12V. Needs only 1µF for stability. Current limiting and thermal Protection. conditions from zero up to the maximum load. Dropout voltage at 100mA output current is exceptionally low: 130mV for the SS673250 and -52, 180mV for the SS6732-33, -34, SS6732-35, -36, -37 and -38. Current limiting and thermal protection are built in to protect the SS6732 against fault conditions. The SS6732 comes in the popular 3-pin SOT-89 package. n APPLICATIONS l l l l l Voltage Regulator for CD-ROM Drivers. Voltage Regulator for LAN Cards. Voltage Regulator for Microprocessor.

GND PIN - Power GND. VIN PIN - Power Supply Input. n APPLICATION INFORMATIONS A capacitor of at least 1uF is required between the device output pin and ground for stability. Without this capacitor the part will oscillate. Even though most types of capacitor may work, the equivalent series resistance (ESR) should be held to 5Ω or less if an Aluminum electrolytic type is used. Many Aluminum electrolytics have electrolytes that freeze at about -30° C, so solid tantalums are recommended for operation below -25 °C. The A capacitor of at least 0.1uF should be placed from the SS6732 input to ground if the lead inductance between the input and power source exceeds 500nH (approximately 10 inches of trace). value of this capacitor may be increased without limit.
