Overview
The LD39020DTPU30R is a fixed-output linear regulator IC from STMicroelectronics, providing a nominal 3.0 V output with a guaranteed maximum current of 200 mA. It operates within an input voltage range of 1.5 V to 5.5 V and features a typical dropout voltage of 200 mV at full load. The device incorporates an internal soft-start circuit and logic-controlled electronic shutdown, reducing standby current to below 0.1 µA. It utilizes a DFN4 1x1 package and includes integrated thermal and short-circuit protection mechanisms.
Feature Summary
- Logic-controlled electronic shutdown for ultra-low power consumption
- Internal soft-start circuit limits inrush current during startup
- Integrated output discharge MOSFET for rapid capacitor discharge
- Built-in constant current and thermal protection
Applications
- Mobile phones
- Tablets
- Digital still cameras (DSC)
- Cordless phones and similar battery-powered systems
- Portable media players
Procurement Notes
Verify the specific suffix 'DT' confirms the inclusion of the auto-discharge feature on this variant. Ensure the ordering code matches the required tolerance level, as the standard version differs from the high-accuracy 'A' version. Confirm the package type corresponds to the DFN4 1x1 footprint requirements for your PCB layout.
Selection Notes
Select this component when a compact solution is needed for low-power battery-operated applications requiring precise voltage regulation. The DFN4 1x1 package offers significant space savings compared to larger alternatives. Consider the internal discharge feature if rapid power-down is necessary for system efficiency.
Part Context
This part belongs to the LD39020 family of very low quiescent current linear regulators designed for mobile and portable electronics. The family supports various output voltages from 0.8 V to 5.0 V in 50 mV steps. The 'D' suffix indicates the presence of the output discharge function, distinguishing it from standard variants without this feature.
Replacement Considerations
LD39020ADTPU30R provides the same functionality but with tighter ±0.5% output voltage tolerance compared to the standard ±2.0% tolerance of the LD39020DTPU30R.
