LOW-VOLTAGE, HIGH-CURRENT 1.8 V LINEAR REGULATOR
The SI-3018LSA is designed to meet the requirement for increased integration and reliability in low-voltage, high-current, linear regulator applications such as personal computers (PCs) and set-top boxes. Each device incorporates a monolithic low-level reference and control circuit with a high-current pnp transistor in a power multi-chip module (PMCM). Regulated output voltages of 2.5 V or 3.3 V are also available. The high-current pass element provides a low dropout voltage with output current to 1 A. Regulator accuracy of ±2 % and excellent temperature characteristics are provided. The logic-compatible ENABLE input gives the designer complete control over power up, power down, and standby or sleep. These devices are supplied in a fully molded 8-lead miniature surface-mount package (tape and reel) with enhanced power-dissipating qualities. They are rated for continuous operation between -30°C and +100°C.
