LD2985AM27R

Overview

The LD2985AM27R is a fixed-output low dropout linear voltage regulator manufactured by STMicroelectronics, providing a stable 2.7 V output with a maximum load current of 150 mA. It features an ultra-low dropout voltage of 280 mV at full load and 7 mV at 1 mA, ensuring high efficiency in battery-powered systems. The device includes a logic-controlled inhibit function on pin 3 for electronic shutdown, reducing quiescent current to less than 1 μA in sleep mode. Internal protections include current limiting and thermal shutdown. It operates within a temperature range of -40 °C to +125 °C and is housed in a compact SOT-23-5L package.

Feature Summary

Ultra-low dropout voltage design for efficient power management in low-voltage applications
Logic-controlled electronic shutdown capability for system standby power reduction
Integrated internal current and thermal protection mechanisms

Applications

Cellular phones
Palmtop laptop computers
Personal digital assistants (PDA)
Camcorders and cameras

Procurement Notes

Verify the specific suffix 'AM27R' against official STMicroelectronics documentation to confirm the 2.7 V fixed output voltage and SOT-23-5L packaging. Ensure compatibility with required input voltage ranges and thermal dissipation requirements for the target application environment before procurement.

Selection Notes

Select this component for designs requiring precise 2.7 V regulation with minimal voltage drop under varying load conditions. Consider its low noise characteristics and small footprint when space-constrained portable electronics are involved. Validate that the 150 mA current limit meets peak demand without triggering thermal protection.

Part Context

This part belongs to the LD2985 family of very low drop and low noise voltage regulators from STMicroelectronics. The series is engineered for low-power and battery-operated devices, offering various fixed output voltages. The AM27R variant specifically targets circuits needing a 2.7 V supply rail with enhanced power efficiency.
