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.

APPLICATIONS

LAN Cards. Wireless Communication Systems. Battery Powered Systems.

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 of output voltage. Typical ground current is approximately 55µA, across the load range 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.
