OM1324STM is a three-terminal precision adjustable positive voltage regulator with an epoxy resin sealed package. It has thermal shutdown, current limiting and safe-area control. With heat sinking, these devices can deliver up to 1.5 amps of output current. The LCC-20 device is limited to .5 amps. The unit also features output voltages that can be fixed from 1.2 volts to 37 volts using external resistors.
The document describes the Omnirel LM117A as a three-terminal, precision adjustable positive voltage regulator supplied in hermetically sealed packages. It features built-in thermal overload protection, short circuit current limiting, and safe-area control. The device can deliver up to 1.5 amps of output current (with specific limits for certain package styles) and allows fixed output voltages from 1.2 volts to 37 volts using external resistors.
The datasheet provides absolute maximum ratings, recommended operating conditions, and detailed electrical characteristics including reference voltage, line regulation, load regulation, ripple rejection, and adjustment pin current across various test conditions. It also includes mechanical outlines for six different package styles: OM1324SMM (SMD-3), OM1324STM (TO-257 Isolated), OM1324NTM (TO-257 Non-Isolated), OM1324NKM (TO-3), OM1324NMM (SMD-1), and OM1324N2M (LCC-20).
