LD2980ABM33TR

Overview

The LD2980ABM33TR is a fixed-output positive low-dropout (LDO) linear voltage regulator manufactured by STMicroelectronics. It provides a stable 3.3V output with a maximum load current of 50mA. The device supports an input voltage range up to 16V and operates within a junction temperature range of -40°C to +125°C. Key electrical characteristics include a typical dropout voltage of 225mV at full load, a quiescent current of 150µA, and a power supply rejection ratio (PSRR) of 63dB at 1kHz. It is housed in a compact SOT-23-5 surface-mount package.

Feature Summary

Ultra-low dropout voltage operation compatible with low ESR output capacitors
Integrated thermal shutdown and current limiting protection circuits
High power supply rejection ratio for noise attenuation
Enable pin control for sleep mode operation

Applications

Battery-powered portable electronic devices
Low-noise analog circuit power supplies
Industrial control systems requiring stable bias voltages
Personal digital assistants and mobile communication equipment

Procurement Notes

Verify the specific suffix 'AB' indicates the required accuracy grade against official datasheets. Confirm the 'TR' designation corresponds to the correct tape-and-reel packaging quantity. Ensure compatibility with RoHS3 environmental standards before finalizing procurement orders.

Selection Notes

Select this component when a fixed 3.3V rail is needed with minimal board space. It is suitable for applications where input-to-output voltage differential is small. Consider the 50mA limit for load requirements. Verify that the system can tolerate the specified quiescent current during active operation.

Part Context

This part belongs to the LD2980 series of ultra-low-dropout regulators designed for low-power applications. It utilizes vertical PNP technology to achieve high performance in a small footprint. The series is engineered for battery-operated systems requiring efficient power management and reliable regulation under varying load conditions.
