The SI-3025LSA 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 1.8V or 3.3V are also available.
The high-current pass element provides a low dropout voltage with output current to 1A. 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.

* Output current rating may be limited by duty cycle, ambient temperature, and heat sinking. Under any set of conditions, do not exceed the specified current rating or a junction temperature of 150˚C.
† Fault conditions that produce excessive junction temperature will activate the device's thermal shutdown circuitry. These conditions can be tolerated but should be avoided.
