Overview
The LDI812C-5.0SFA is a fixed-output linear voltage regulator manufactured by Diotec Semiconductor, designed for surface-mount applications in the SOT-23-5 package. It provides a nominal output voltage of 5.0 V with a tolerance range of 4.9 V to 5.1 V. The device supports an input voltage up to 16 V and delivers a maximum output current of 500 mA. Key electrical characteristics include a dropout voltage between 160 mV and 300 mV and a quiescent current of 1 µA. It operates within a temperature range of -40°C to +125°C.
Feature Summary
- Fixed 5.0 V output voltage with tight tolerance
- Low dropout voltage for efficient power management
- Ultra-low quiescent current consumption
- Compact SOT-23-5 surface-mount packaging
Applications
- Portable battery-powered electronic devices
- Embedded systems requiring stable 5 V logic supply
- Industrial control modules
- Consumer electronics power regulation
Procurement Notes
Verify the specific suffix 'SFA' against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications and marking codes. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the Mouser part number 637-LDI812C-5.0SFA for accurate distributor availability and lead times. Confirm thermal performance matches your PCB layout constraints.
Selection Notes
Select this regulator when a stable 5 V rail is required from a higher voltage source (up to 16 V) with minimal current draw. The low dropout characteristic makes it suitable for batteries nearing depletion. The SOT-23-5 package is ideal for space-constrained designs. Ensure the input voltage does not exceed the absolute maximum rating to prevent device failure.
Part Context
This component belongs to Diotec Semiconductor's LDI812C series of low-dropout linear regulators. The series is characterized by high stability and low noise, making it suitable for sensitive analog and digital circuits. The LDI812C-5.0SFA specifically targets applications needing a precise 5 V output in a compact form factor.
Replacement Considerations
Check for direct pin-compatible replacements within the same LDI812C family or other manufacturers offering SOT-23-5 LDOs with 5.0 V output and similar current ratings. Verify that any substitute maintains the same dropout voltage and quiescent current specifications to ensure circuit compatibility.
