AS1369-BWLT-30

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The AS1369-BWLT-30 is a 200mA ultra-compact low dropout regulator with a fixed 3.0V output, manufactured by ams OSRAM USA INC. It operates within an input voltage range of 2.0V to 5.5V and delivers high accuracy of ±2% over temperature. The device features a typical quiescent current of 25µA and standby current below 0.1µA. It provides excellent noise performance at 30µVRMS without requiring external bypass capacitance. Packaged in a 4-bump WL-CSP with 0.5mm pitch, it supports mobile phones, PDAs, and other battery-powered devices.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific ordering code AS1369-BWLT-30 against official manufacturer documentation to confirm the fixed 3.0V output specification. Ensure compatibility with the required 4-bump WL-CSP footprint during PCB layout. Confirm RoHS compliance status through the latest datasheet revision before finalizing procurement plans.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 3.0V rail is required for compact mobile or portable electronics. The low dropout characteristic allows operation from single-cell lithium batteries. Verify that the load current does not exceed 200mA and that the input voltage remains within the specified operational range for optimal line regulation.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

The AS1369 belongs to a family of ultra-compact low dropout regulators designed for battery-powered applications. This series offers multiple fixed output voltage options ranging from 1.2V to 5.0V in 100mV steps. All variants share the same 4-bump WL-CSP package and core electrical characteristics, differing primarily in their regulated output voltage levels.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Other AS1369 variants with different output voltages (e.g., AS1369-BWLT-28 for 2.8V) are pin-compatible but provide different regulated outputs. Direct substitution requires verifying that the alternative voltage matches the system requirements.
