AS1320-BSOT-33

Overview

The AS1320-BSOT-33 is a boost switching regulator IC manufactured by ams OSRAM. It provides a fixed positive output voltage of 3.3 V with an output current capacity of 200 mA. The device operates within an input voltage range of 700 mV to 5 V and functions in an ambient temperature range of -40°C to +85°C. It is housed in a SOT-23-6 package.

Feature Summary

• Boost switching regulator topology for voltage step-up applications
• Fixed positive output configuration
• Compact surface-mount packaging

Applications

• Portable electronic devices requiring voltage boosting
• Battery-powered systems needing stable 3.3 V supply
• General-purpose power management in compact electronics

Procurement Notes

Verify the specific suffix BSOT against official datasheets to confirm the SOT-23-6 package variant. Confirm the fixed 3.3 V output specification matches system requirements. Ensure thermal operating limits align with the intended application environment. Cross-reference manufacturer part numbers to avoid confusion with similar series components.

Selection Notes

Select this component when a compact boost regulator is needed for low-voltage input sources up to 5 V. The fixed 3.3 V output suits digital logic supplies. Consider the 200 mA current limit for load requirements. The SOT-23-6 package offers space efficiency for dense PCB layouts.

Part Context

This part belongs to the AS1320 series of boost regulators from ams OSRAM. It is designed for portable applications where space and efficiency are critical. The series typically includes variants with different output voltages and packages, such as the SOT-23-6 form factor shown here.

Replacement Considerations

Check for direct pin-compatible alternatives within the same manufacturer's portfolio. Verify that substitute parts maintain the 3.3 V output and 200 mA current capability. Ensure the replacement supports the same input voltage range and operating temperature specifications.
