Product Summary

The lm1117mpx-adj is a Low-Dropout Linear Regulator. The lm1117mpx-adj is a series of low dropout voltage regulators with a dropout of 1.2V at 800mA of load current. It has the same pin-out as National Semiconductor’s industry standard LM317. The lm1117mpx-adj is available in an adjustable version, which can set the output voltage from 1.25V to 13.8V with only two external resistors. In addition, it is also available in five fixed voltages, 1.8V, 2.5V, 2.85V, 3.3V, and 5V. The lm1117mpx-adj offers current limiting and thermal shutdown. Its circuit includes a zener trimmed bandgap reference to assure output voltage accuracy to within ±1%. The lm1117mpx-adj is available in LLP, TO-263, SOT-223, TO-220, and TO-252 D-PAK packages. A minimum of 10μF tantalum capacitor is required at the output to improve the transient response and stability. The applications of the lm1117mpx-adj include 2.85V Model for SCSI-2 Active Termination, Post Regulator for Switching DC/DC Converter, High Efficiency Linear Regulators Battery Charger and Battery Powered Instrumentation.
