SI-3033LSA, Regulator

SI-3033LSA LOW-VOLTAGE, HIGH-CURRENT 3.3 V LINEAR REGULATOR The SI-3033LSA 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 1.8 V or 2.5 V are also available.
