三，安培固定正稳压器 THREE-AMPERE POSITIVE FIXED VOLTAGE REGULATORS

This family of fixed voltage regulators are monolithic integrated circuits capable of driving loads in excess of 3.0 A. These three−terminal regulators employ internal current limiting, thermal shutdown, and safe−area compensation. Devices are available with improved specifications, including a 2% output voltage tolerance, on AC−suffix 5.0 V, 12 V and 15 V device types. Although designed primarily as a fixed voltage regulator, these devices can be used with external components to obtain adjustable voltages and currents. This series of devices can be used with a

series−pass transistor to supply up to 15 A at the nominal output voltage.
