Overview
The LE52ABD is a positive fixed linear voltage regulator (LDO) manufactured by STMicroelectronics. It provides a fixed output voltage of 5.2V with a maximum load current of 100mA. The device accepts input voltages up to 18V and features a maximum dropout voltage of 0.5V at full load. It is housed in an 8-SOIC package, designed for space-sensitive applications.
Feature Summary
- Very low drop voltage operation for efficient power management
- Integrated inhibit function for power control
- Compact SOIC package suitable for space-constrained designs
Applications
- Handheld devices requiring compact power regulation
- Battery-powered systems needing low dropout performance
- Space-sensitive electronic circuits
Procurement Notes
Verify the component authenticity through official STMicroelectronics channels or authorized distributors. Confirm the part number matches the specific datasheet revision. Check for RoHS compliance status as indicated in the manufacturer documentation. Ensure the package type corresponds to your PCB design requirements before procurement.
Selection Notes
Select this component when a fixed 5.2V output is required with a 100mA current capacity. Consider the 18V maximum input voltage limit for system design. The 8-SOIC package is appropriate for surface-mount assembly in compact layouts. Evaluate the 0.5V dropout specification against your minimum input-output voltage differential requirements.
Part Context
This part belongs to STMicroelectronics' family of very low drop voltage regulators with inhibit functionality. These regulators are designed for applications requiring stable voltage regulation with minimal power loss across the pass element. The series supports various fixed output voltages and packages to meet diverse design constraints.
Replacement Considerations
Consult STMicroelectronics documentation for direct pin-compatible alternatives within the same LDO family. Verify that substitute parts match the 5.2V output, 100mA current rating, and 8-SOIC package dimensions. Cross-reference electrical specifications including dropout voltage and input voltage range to ensure functional equivalence.
