Overview
The LD2980CM33TR is a positive LDO linear voltage regulator manufactured by STMicroelectronics. It provides a fixed 3.3 V output with a maximum continuous current of 50 mA. The device operates with an input voltage range up to 16.0 V and features a typical dropout voltage of 0.12 V at 50 mA load. Quiescent current is specified at 80 µA in active mode, dropping below 1 µA when the inhibit pin is pulled low for shutdown. It utilizes a SOT-23-5L package.
Feature Summary
- Compatible with low ESR ceramic output capacitors
- Logic-controlled electronic shutdown via inhibit pin
- Internal current and thermal limiting protection
Applications
- Battery powered systems
- Low noise applications
- Instrumentation
- Industrial control boards
Procurement Notes
Verify the specific suffix 'CM33TR' against the manufacturer datasheet to confirm the fixed 3.3V output voltage and SOT-23-5L package configuration. Ensure compatibility with low ESR ceramic capacitors as required by the design specifications. Confirm that the inhibit pin logic levels align with the system's control signals before finalizing procurement.
Selection Notes
Select this component for designs requiring ultra-low dropout performance and minimal quiescent current consumption. It is suitable for battery-operated devices where power efficiency is critical. The inclusion of a shutdown function allows for effective standby power management. Verify that the required load current does not exceed the 50 mA limit.
Part Context
This part belongs to the LD2980 series of ultra-low drop voltage regulators from STMicroelectronics. The series is characterized by its ability to operate with low ESR ceramic capacitors, reducing board space and cost. The LD2980 family offers various fixed output voltages and includes logic-controlled shutdown capabilities for enhanced power management in portable electronics.
Replacement Considerations
Check for direct cross-references such as LD2981CM33TR if higher current capacity is needed. Verify pinout compatibility and electrical parameters like dropout voltage and quiescent current when substituting with other LDO regulators from different manufacturers.
