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 (PMCMTM). Regulated output voltages of 1.8 V or 2.5 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.
