Overview
The LD56020M100R is a high-accuracy linear voltage regulator from STMicroelectronics, providing a fixed 1.0 V output with a guaranteed maximum current of 200 mA. It operates within an input voltage range of 1.1 V to 5.5 V and features ultra-low dropout performance, reaching up to 200 mV at full load in the SOT23-5L package. The device maintains low quiescent current of 25 µA typical and standby consumption below 1 µA. It includes logic-controlled shutdown, thermal protection, and short-circuit foldback.
Feature Summary
- Ultra-low noise performance with 8.8 µVRMS output noise over a 10 Hz to 100 kHz bandwidth
- Logic-controlled electronic shutdown function enabling deep sleep mode with minimal power draw
- Integrated thermal shutdown and short-circuit current foldback for robust fault protection
- Output active discharge feature to rapidly reduce output voltage upon shutdown
Applications
- Smartphones and tablets
- Image sensors
- VCO and RF modules
Procurement Notes
Verify that the specific ordering code matches the required SOT23-5L package and 1.0 V output configuration. Confirm environmental compliance status via ECOPACK specifications on the manufacturer website. Ensure application circuits utilize recommended ceramic capacitors between 0.7 µF and 10 µF to maintain stability across the operating temperature range.
Selection Notes
Select this component when space-constrained designs require a low-noise LDO with precise 1.0 V regulation. The SOT23-5L package offers a compact footprint suitable for portable electronics. Consider the 200 mA current limit and 1.1 V minimum input voltage when designing battery-powered systems requiring efficient power management.
Part Context
This part belongs to the LD56020 family of ultra-low dropout regulators designed for low-power applications. The series supports various fixed output voltages ranging from 0.6 V to 4.0 V in 50 mV steps. Other variants include the Flip-Chip4 package option and different output configurations such as the LD56020J120R.
Replacement Considerations
Compatible alternatives within the same family include LD56020M110R (1.1 V) and LD56020M120R (1.2 V). For identical functionality with a different package, consider the Flip-Chip4 variant LD56020J100R.
