AS1369-BWLT-28-10K

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

The AS1369-BWLT-28-10K is a 2.8V fixed-output, 200mA ultra-compact low dropout regulator from the AS1369 series by ams OSRAM. It operates with an input voltage range of 2.0V to 5.5V and delivers high accuracy within ±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 (0.5mm pitch), it includes thermal and over-current protection for reliable operation in battery-powered mobile devices.

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

Verify the specific ordering code AS1369-BWLT-28-10K against official manufacturer documentation to confirm availability and exact specifications. Ensure compatibility with standard surface mount assembly processes for 4-bump WL-CSP packages. Confirm RoHS compliance status through authorized distributors or direct manufacturer channels prior to procurement.

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

Select this component when a fixed 2.8V output is required for low-power mobile electronics. It is suitable for designs needing minimal external components due to its stability with small capacitors. Consider the 4-bump WL-CSP footprint constraints during PCB layout. Verify that the input voltage remains above the minimum operating threshold for optimal dropout performance.

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 consumer electronics. Manufactured by ams OSRAM (formerly austriamicrosystems), these devices prioritize low noise and high efficiency in minimal footprints. The series offers multiple fixed voltage options ranging from 1.2V to 5.0V, catering to various logic levels in portable devices.

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

Direct substitutes include other AS1369 variants with different fixed output voltages, such as AS1369-BWLT-25 (2.5V) or AS1369-BWLT-30 (3.0V). Cross-referencing with other 200mA LDOs in 4-bump WL-CSP packages may be necessary if pinouts differ. Always verify electrical characteristics and package dimensions before substitution.
