Overview
The LD2985BM30R is a fixed-output low-dropout voltage regulator manufactured by STMicroelectronics, providing a stable 3 V output with a maximum load current of 150 mA. It operates within an input voltage range of 2.5 V to 16 V and features an ultra-low dropout voltage of 280 mV at full load. The device incorporates logic-controlled electronic shutdown via a TTL-compatible inhibit pin, reducing quiescent current to less than 1 μA in sleep mode. Internal protections include current limiting and thermal shutdown. It is housed in a compact SOT-23-5L package and supports an operating temperature range from -40 °C to +125 °C.
Feature Summary
- Logic-controlled electronic shutdown for power management
- Ultra-low dropout voltage for battery efficiency
- Integrated current and thermal protection mechanisms
Applications
- Cellular phones
- Palmtop laptop computers
- Personal digital assistants (PDA)
- Camcorders and cameras
Procurement Notes
Verify the specific suffix BM30R confirms the 3 V fixed output variant. Ensure the ordering code matches the required SOT-23-5L surface-mount package configuration. Confirm that the manufacturer designation aligns with STMicroelectronics specifications before finalizing procurement orders.
Selection Notes
Select this component when a fixed 3 V rail is required for noise-sensitive portable electronics. The low quiescent current and small footprint make it suitable for space-constrained designs. Verify that the application does not require adjustable output voltages or higher current capabilities beyond 150 mA.
Part Context
This part belongs to the LD2985 family of very low drop and low noise voltage regulators. The series offers various fixed output voltages including 1.8 V, 2.5 V, 2.8 V, 3.1 V, 3.3 V, and 5 V variants. All members share the same core architecture featuring inhibit functionality and low noise performance.
Replacement Considerations
Other LD2985 variants with different output voltages may serve as functional replacements if the system voltage requirement changes. Ensure the replacement maintains the SOT-23-5L package and compatible electrical characteristics.
