The SPX3819S-1.2 is a low dropout (LDO) voltage regulator manufactured by Sipex Corporation (now part of Exar Corporation). LDO regulators provide a stable output voltage from a varying input voltage while minimizing the voltage drop across the regulator. The '-1.2' indicates a fixed output voltage of 1.2V.

Applications

• Portable devices
• Battery-powered equipment
