Overview
The LD2982AM15R is a fixed-output low-dropout linear voltage regulator manufactured by STMicroelectronics. It provides a stable 1.5 V output with a maximum current capacity of 50 mA. The device features an ultra-low dropout voltage and low quiescent current, making it suitable for noise-sensitive applications. It includes a logic-controlled inhibit function to manage power consumption. The component is housed in an SC-74A (SOT-753) surface-mount package.
Feature Summary
- Logic-controlled inhibit function for power management
- Ultra-low dropout voltage characteristics
- Low noise performance suitable for sensitive circuits
- Fixed 1.5 V output configuration
Applications
- Low noise voltage regulation
- Portable electronic devices
- Battery-powered systems
Procurement Notes
Verify the exact part number LD2982AM15R against official STMicroelectronics documentation to confirm the 1.5 V fixed output and SC-74A package. Ensure compatibility with system requirements for 50 mA load current and logic-level inhibit signals before procurement.
Selection Notes
Select this component when a fixed 1.5 V supply is required with minimal voltage drop and low noise. The inhibit feature allows for external control of the regulator state. Verify that the 50 mA output current meets the load demands and that the SC-74A package fits the PCB layout constraints.
Part Context
This regulator belongs to the LD2982 series from STMicroelectronics, designed for low-dropout operation. The series offers variants with different output voltages and packages. The LD2982AM15R specifically targets applications requiring stable, low-noise power delivery in compact form factors.
Replacement Considerations
Check for other LD2982 series variants with compatible output voltages and packages. Verify pinout and electrical specifications against official datasheets before substitution.
