Overview
The LDCL015MR is an ultra-low-dropout linear regulator IC manufactured by STMicroelectronics. It provides a maximum output current of 150 mA with an input voltage range spanning from 1.8 V to 5.5 V. The device features a typical dropout voltage of 50 mV at 100 mA load. It supports adjustable output voltage starting from 0.87 V and utilizes a SOT-23-5 package for compact integration.
Feature Summary
- Capless design eliminates the need for external output capacitors
- Ultra-low dropout voltage ensures high efficiency under minimal headroom conditions
- Adjustable output voltage allows flexible system configuration
Applications
- Battery-powered portable devices requiring efficient power management
- Systems operating with low input voltage margins
- Compact electronics where board space is limited
Procurement Notes
Verify the specific suffix 'MR' indicates the correct tape-and-reel packaging format required for automated assembly processes. Confirm that the adjustable output configuration aligns with your external resistor network design. Ensure input voltage constraints remain within the specified 1.8 V to 5.5 V range during operation.
Selection Notes
Select this component when capacitor-free operation is mandatory to reduce bill of materials and footprint. It is suitable for applications needing precise voltage adjustment rather than fixed outputs. Consider the thermal performance in the SOT-23-5 package relative to the expected load current and ambient temperature conditions.
Part Context
This part belongs to the LDCL015 family of ultra-low-dropout regulators designed for space-constrained and battery-operated applications. The series emphasizes simplicity through capless operation while maintaining stable regulation across varying load conditions and input voltage fluctuations.
Replacement Considerations
Check for direct pin-compatible alternatives within the same manufacturer's portfolio that offer similar current ratings and dropout characteristics. Verify that any substitute maintains the capless requirement if PCB layout cannot be modified.
FAQ
Does the LDCL015MR require an output capacitor?
No, it is designed as a capless regulator, eliminating the need for external output capacitors.
What is the minimum input voltage for operation?
The device operates with an input voltage ranging down to 1.8 V.
