Overview
The LDK320AM15R is a positive adjustable low-dropout linear voltage regulator manufactured by STMicroelectronics. It provides an output current up to 200 mA with an input voltage range of 2.5 V to 18 V. The device features a typical dropout voltage of 100 mV at 100 mA load and a quiescent current of 60 μA, reducing to less than 1 μA in shutdown mode via the enable pin. It includes logic-controlled electronic shutdown, short-circuit current limiting, thermal protection, and SOA protection. The component is housed in a SOT-23-5L surface-mount package.
Feature Summary
- Logic-controlled electronic shutdown for ultra-low power consumption
- High power supply rejection ratio (PSRR) for noise reduction
- Integrated short-circuit, thermal, and safe operating area protections
- Compatible with ceramic output capacitors
Applications
- Digital Signal Controllers (DSC)
- Television systems
- Blu-ray and DVD players
- Personal computers
- Industrial equipment
Procurement Notes
Verify the specific suffix 'AM15R' against official documentation to confirm it denotes the adjustable version with ±0.5% accuracy tolerance. Ensure the ordering code matches the required SOT-23-5L package configuration. Confirm RoHS compliance status through the manufacturer's latest environmental declarations before finalizing procurement specifications.
Selection Notes
Select this component for designs requiring high accuracy and low noise regulation from battery-powered sources. The adjustable output allows flexible voltage setting within the specified range. Consider the SOT-23-5L package for space-constrained layouts. Verify that the application circuit utilizes compatible ceramic capacitors to ensure stability across the full operating temperature range.
Part Context
This part belongs to the LDK320 series of low-dropout regulators designed for low-power applications. The series offers various fixed and adjustable output options with high PSRR characteristics. The LDK320AM15R specifically represents the adjustable variant optimized for precision requirements, utilizing advanced bandgap reference technology for stable performance under varying load conditions.
Replacement Considerations
Consult the manufacturer's datasheet for officially confirmed substitute part numbers within the LDK320 family or equivalent regulatory alternatives. Verify pin compatibility and electrical parameter alignment before substitution.
