St MicroElectronics 12V 500mA Fixed Linear Voltage Regulator TO-252 (DPAK)

St MicroElectronics 12V 500mA Fixed Linear Voltage Regulator is a three-terminal, positive fixed linear voltage regulator with a nominal 12V output and a maximum output current of 500mA. It is designed to provide local on-card power supply regulation, which avoids the distribution problems associated with relying on a single, centralised point of regulation and can support more stable system performance.

Overview

Supplied in a TO-252-3 (DPAK) surface mount package, this regulator accepts an input voltage range of 19V to 35V and delivers a fixed 12V output. Its internal protection features include advanced current limiting, thermal shutdown and safe operating area (SOA) protection, helping to safeguard both the regulator and the circuitry it supplies. Short-circuit protection and output transition SOA protection are also included.
