Overview
The LF50CPT-TRY is a positive fixed linear voltage regulator from the LFxx series, manufactured by STMicroelectronics. It provides a fixed output voltage of 5V with a maximum output current of 500mA. The device features a very low dropout voltage of 0.45V and a low quiescent current of 50uA. It operates within an input voltage range up to 16V and supports a junction temperature range from -40°C to +125°C. The component is housed in a PPAK surface-mount package.
Feature Summary
- Very low dropout voltage for efficient power management
- Low quiescent current suitable for battery-powered systems
- Integrated thermal overload and short-circuit protection
Applications
- Battery-powered electronic systems
- Low-noise power supply circuits
- Low-power application environments
Procurement Notes
Verify the specific suffix 'TRY' against official manufacturer documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with required operating temperatures and load conditions. Cross-reference datasheets for pinout accuracy and thermal performance characteristics before integration into final designs.
Selection Notes
Select this component for applications requiring a stable 5V rail with minimal voltage drop under moderate loads. Consider its low static current for energy efficiency in portable devices. Evaluate thermal dissipation requirements based on the PPAK package and expected ambient temperatures to ensure reliable operation within specified limits.
Part Context
This part belongs to the LFxx family of low-dropout regulators designed for general-purpose voltage regulation. The LF50 variant specifically targets 5V output applications. The PPAK packaging facilitates surface-mount assembly, offering a compact solution for space-constrained printed circuit board layouts while maintaining robust electrical performance.
Replacement Considerations
Consult official substitution lists for equivalent LDO regulators with matching 5V output and 500mA current capabilities. Verify pin compatibility and package dimensions when considering alternatives from other manufacturers or different product lines within the same family.
