Overview
The LDK220M30R is a fixed-output linear voltage regulator from STMicroelectronics, providing a stable 3V output with a maximum current of 200mA. It operates within an input voltage range of 2.5V to 13.2V and features a typical dropout voltage of 100mV at 100mA load. The device incorporates low quiescent current (typical 55µA) and logic-controlled shutdown functionality that reduces consumption below 1µA. It includes internal short-circuit constant current limiting and thermal protection, ensuring reliability in battery-powered applications.
Feature Summary
- Logic-controlled electronic shutdown for ultra-low power consumption
- Internal short-circuit constant current limiting and thermal protection
- Compatible with ceramic capacitors for stability
Applications
- Battery-powered portable devices
- Handheld equipment requiring low noise regulation
- Embedded systems needing reliable linear voltage regulation
Procurement Notes
Verify the specific package variant SOT-23-5 against design requirements. Confirm RoHS3 compliance status for environmental regulations. Ensure input voltage does not exceed the 13.2V maximum rating during operation. Check thermal dissipation capabilities within the -40°C to 125°C junction temperature range.
Selection Notes
Select this component when a fixed 3V output is required with minimal external components. The low dropout characteristic suits applications where input voltage is close to the output level. The enable pin allows for system power management integration. Verify capacitor compatibility to maintain stability without additional compensation networks.
Part Context
This part belongs to the LDK220 family of low-dropout regulators designed for handheld and portable applications. The series offers various fixed output voltages and adjustable options. It is characterized by low noise and low quiescent current, making it suitable for sensitive analog circuits in consumer electronics.
Replacement Considerations
Consult official documentation for direct substitutes within the LDK220 series or comparable STMicroelectronics LDOs with matching voltage and current ratings.
