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 55 µA, under output conditions from zero up to the maximum load. Dropout voltage at 100mA output current is exceptionally low: 130mV for the SS6732- 50 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 TYPICAL APPLICATION CIRCUIT VOUT VOUT GND VIN 1µF CIN VIN 10µF COUT Low Dropout Linear Regulator SS6732 Rev.2.01 6/26/2003

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 value of this capacitor may be increased without limit. 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).
