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.
