Overview
The LD56020M110R is a low-dropout linear regulator manufactured by STMicroelectronics, providing a fixed 1.1 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 characteristics, reaching up to 190 mV at full load. The device maintains high accuracy with ±2% tolerance over temperature and ±1% at 25 °C. It incorporates logic-controlled electronic shutdown for standby currents below 0.1 µA, thermal protection, and active output discharge.
Feature Summary
- Ultra-low noise performance with 8.8 µVRMS output noise in the 10 Hz to 100 kHz bandwidth
- Logic-controlled enable pin allows deep shutdown mode with minimal power consumption
- Integrated thermal shutdown and short-circuit current foldback protection mechanisms
- Stabilized using small ceramic capacitors on both input and output terminals
Applications
- Smartphones and tablets
- Image sensors
- VCO and RF modules
Procurement Notes
Verify that the ordering suffix 'M' corresponds to the SOT23-5L package configuration as specified in the official datasheet order codes. Confirm the 'R' suffix indicates tape and reel packaging. Ensure the specific 1.1 V output variant matches the design requirements before finalizing procurement orders.
Selection Notes
Select this component when space-constrained designs require a compact SOT23-5L footprint alongside precise voltage regulation. The low quiescent current and ultra-low dropout make it suitable for battery-operated systems where efficiency and extended runtime are critical. Verify capacitor ESR ranges to ensure stability across the operating temperature spectrum.
Part Context
This part belongs to the LD56020 family of high-accuracy voltage regulators designed for low-power applications. The series offers various fixed output voltages and package options, including Flip-Chip4 and SOT23-5L. The M110R designation specifically identifies the 1.1 V output version housed in the SOT23-5L package.
Replacement Considerations
Other variants within the LD56020 family, such as LD56020J110R (Flip-Chip4) or different voltage outputs like LD56020M100R, share similar electrical characteristics but differ in physical package dimensions.
