AS1369-BWLT-12

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

The AS1369-BWLT-12 is a 200mA ultra-compact low dropout regulator with a fixed 1.2V output, operating within a 2.0V to 5.5V input range. It delivers high accuracy of ±2% over temperature and features a typical quiescent current of 25µA, dropping below 0.1µA in standby. The device provides 72dB PSRR at 1kHz and 30µVRMS noise without requiring external bypass capacitors. Packaged in a 4-bump WL-CSP with 0.5mm pitch, it includes thermal shutdown and overcurrent protection for mobile and battery-powered applications.

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

Verify the specific ordering code suffix against the manufacturer's official documentation to confirm the exact output voltage and package configuration. Ensure compatibility with the required 4-bump WL-CSP footprint during PCB layout. Confirm that the component meets RoHS compliance standards for your target market regulations before finalizing procurement plans.

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

Select this component when system design requires minimal board space alongside precise voltage regulation for sensitive analog or digital loads. The low dropout characteristic supports operation near battery depletion levels. Verify that the load current does not exceed the 200mA limit 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

This part belongs to the AS1369 series of ultra-compact low dropout regulators manufactured by austriamicrosystems AG. The series offers multiple fixed output voltage options ranging from 1.2V to 5.0V in 100mV steps. All variants share the same physical package and core electrical characteristics, differing primarily in their regulated output voltage settings.

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

Direct replacements must match the 4-bump WL-CSP package dimensions and 1.2V fixed output. Verify equivalent PSRR, quiescent current, and thermal protection specifications. Cross-reference pin assignments for VIN, VOUT, GND, and EN to ensure functional compatibility without circuit redesign.
