- Low dropout voltage performance
- Compact TO-92-3 package design
Applications
- Battery-powered portable devices
- General purpose voltage regulation
- Embedded system power supplies
Procurement Notes
Verify the obsolete status of this component before procurement planning. Confirm RoHS compliance and lead-free status through official documentation. Check for available substitute parts from STMicroelectronics or authorized distributors if inventory acquisition is required for production.
Selection Notes
Select this regulator for applications requiring a fixed 4V supply with moderate current demands up to 100mA. Ensure the input voltage exceeds the output by at least the specified dropout voltage. Consider the thermal dissipation capabilities inherent to the TO-92-3 package when designing the circuit layout.
Part Context
This component belongs to the LE40 series of linear regulators from STMicroelectronics. It is categorized under PMIC (Power Management Integrated Circuits) specifically as a linear LDO regulator. The series is known for providing reliable fixed-voltage outputs in small packages suitable for space-constrained electronics.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Consult STMicroelectronics technical support or authorized distributor catalogs for direct replacements or pin-compatible alternatives.
