LD39080DT12-R

Overview

The LD39080DT12-R is an ultra low-drop BiCMOS voltage regulator manufactured by STMicroelectronics. It provides a guaranteed output current of 0.8 A with an operating input voltage range from 2.5 V to 6 V. The device features an adjustable output voltage ranging from 1.22 V to 5.0 V, utilizing a reference voltage of 1.22 V. Quiescent current is typically 1 mA at full load and drops to a maximum of 1 µA in off mode. Dropout voltage is specified as 150 mV typical at 0.8 A load and 20 mV typical at 150 mA load. The regulator operates within a temperature range of -40 °C to +125 °C and includes internal current and thermal limits.

Feature Summary

Ultra low dropout voltage performance across the full load current range
Logic-controlled electronic shutdown for reduced power consumption
Internal short-circuit and thermal protection mechanisms
Stable operation with ceramic output capacitors

Applications

Microprocessor power supply
DSP power supply
Post regulators for switching suppliers
High efficiency linear regulator

Procurement Notes

Verify the specific suffix DT12 against official documentation to confirm fixed output voltage configuration versus adjustable variants. Confirm package type PPAK availability and tape-and-reel specifications. Check current production status as datasheets may indicate lifecycle changes. Ensure component authenticity through authorized distribution channels.

Selection Notes

Select this regulator for applications requiring high efficiency under heavy loads due to its ultra low dropout characteristics. Consider the BiCMOS process benefits for maintaining low quiescent current regardless of load. Evaluate thermal management requirements given the PPAK package dimensions and thermal resistance values. Ensure external capacitor selection meets stability criteria regarding capacitance and ESR ranges.

Part Context

This component belongs to the LD39080 series of ultra low drop BiCMOS voltage regulators. The series is designed for low voltage microprocessors and memory applications where efficiency and low noise are critical. The PPAK package offers a compact solution suitable for space-constrained designs while providing adequate thermal dissipation capabilities.
