AS1312-BWLT-33

Overview

The AS1312-BWLT-33 is a switching voltage regulator manufactured by ams OSRAM. It operates with an input voltage range from 700 mV to 5 V and provides a fixed output of 3.3 V. The device delivers an output current of 200 mA through a single output channel. It is housed in a WLCSP-8 package suitable for surface mount installation. The component functions within a temperature range of -40°C to +85°C.

Feature Summary

• Single-output step-down switching regulator topology
• Ultra-low minimum input voltage capability
• Compact wafer-level chip scale packaging

Applications

• Portable electronic devices requiring low input voltage regulation
• Battery-powered systems with varying supply levels
• Space-constrained mobile applications

Procurement Notes

Verify the End of Life status before design finalization, as the component is listed as discontinued. Confirm availability through authorized distributors or secondary markets if sourcing is required. Ensure compatibility with existing PCB footprints and reflow profiles specific to WLCSP packages during manufacturing integration.

Selection Notes

Select this component when a low-profile solution is needed for regulating voltages from sources starting below 1 V. The fixed 3.3 V output suits standard logic levels. Consider the limited output current capacity for load requirements. Verify thermal management needs despite the small form factor.

Part Context

This part belongs to the AS1312 series of power management integrated circuits. It falls under the Switching Voltage Regulators category within PMICs. The manufacturer, ams OSRAM, specializes in light and sensor solutions, extending into power management for compact electronics.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the End of Life status, alternative components must be identified based on electrical equivalence and pin compatibility through independent engineering analysis.
