Overview
The LD56020J100R is a high-accuracy, ultra-low noise linear voltage regulator manufactured by STMicroelectronics. It provides a fixed output voltage of 1.0 V with a guaranteed maximum output current of 200 mA. The device operates within an input voltage range of 1.1 V to 5.5 V and features an ultra-low dropout voltage of up to 90 mV at 50 mA load. Key electrical specifications include a typical quiescent current of 20 µA, standby current below 1 µA, and an output noise voltage of 8.8 µVRMS over the 10 Hz to 100 kHz bandwidth. It utilizes a Flip-Chip4 package measuring 0.65 x 0.65 mm².
Feature Summary
- Ultra-low noise performance suitable for sensitive RF and analog circuits
- Logic-controlled electronic shutdown with extremely low standby consumption
- Integrated thermal protection and short-circuit current foldback
- Output active discharge function for rapid power-down
Applications
- Smartphones and tablets
- Image sensors
- VCO and RF modules
Procurement Notes
Verify that the specific ordering code matches the required package type and output voltage tolerance. Confirm environmental compliance status such as ECOPACK grades directly with the manufacturer or authorized distributors. Ensure application circuit designs adhere to recommended input and output capacitor values to maintain stability under all operating conditions.
Selection Notes
Select this component when space constraints require a compact Flip-Chip4 footprint alongside strict low-noise requirements. It is appropriate for battery-operated systems due to its low ground current and efficient shutdown mode. Consider the SOT23-5L variant if through-hole or different surface-mount compatibility is necessary for the design.
Part Context
This part belongs to the LD56020 family of low-input-voltage, 200 mA ultra-low dropout linear regulators. The series offers various fixed output voltages in 50 mV steps ranging from 0.6 V to 4.0 V. Available packages include the highly compact Flip-Chip4 and the standard SOT23-5L, catering to diverse space-saving needs in portable electronics.
Replacement Considerations
Other members of the LD56020 family, such as LD56020M100R (SOT23-5L) or LD56020J110R (Flip-Chip4), share identical electrical characteristics and pinouts. These can serve as functional substitutes provided the specific output voltage and package form factor align with the existing board layout and design requirements.
FAQ
What is the typical output noise voltage specification?
The LD56020J100R specifies an ultra-low output noise voltage of 8.8 µVRMS measured between 10 Hz and 100 kHz.
How does the enable pin function?
The enable pin controls the device state; setting it high turns the regulator on, while setting it low activates the shutdown mode, reducing total current consumption to less than 0.1 µA.
