LDL112PV33R

Overview

The LDL112PV33R is a fixed-output low-dropout linear regulator manufactured by STMicroelectronics, providing a stable 3.3V output with a maximum current capacity of 1.2A. It operates within an input voltage range of up to 5.5V and features a typical dropout voltage of 0.6V at full load. The device incorporates reverse current protection, enabling safe operation in battery-powered systems where backflow prevention is critical. With a quiescent current of 70 µA and power supply rejection ratio of 57dB at 1kHz, it ensures efficient performance. Packaged in a compact 6-DFN (3x3 mm) surface-mount format, it supports junction temperatures from -40°C to 125°C.

Feature Summary

Reverse current protection prevents backward flow when input voltage drops below output level
Logic-controlled enable pin allows electronic shutdown with ultra-low standby consumption
Integrated thermal and current limiting safeguards against overload conditions
Compatible with small ceramic output capacitors for minimal footprint design

Applications

Battery-powered portable electronics requiring extended runtime
Systems needing isolation between input source and output load during power-down
Low-noise analog circuit power supplies
Embedded microcontroller core voltage regulation

Procurement Notes

Verify the complete part number including suffix 'R' to confirm tape-and-reel packaging configuration. Confirm RoHS3 compliance status through official ST documentation prior to integration. Ensure ESD handling protocols are followed due to sensitive semiconductor construction. Cross-reference datasheet revision dates to validate parameter consistency with design requirements.

Selection Notes

Choose this component when reverse current blocking is essential alongside low quiescent current operation. The 3.3V fixed output suits digital logic families requiring precise rail stability. Evaluate thermal dissipation needs based on expected load current and ambient temperature constraints within the specified operating range.

Part Context

Part of the LDL112 family offering high-current LDO solutions with enhanced protection features. Designed for applications demanding both efficiency and safety in power management architectures.
