LDL112PU10R

Overview

The LDL112PU10R is a low-dropout linear regulator from STMicroelectronics, providing a fixed 1.0 V output with a maximum current of 1.2 A. It operates within an input voltage range of 1.6 V to 5.5 V and features a typical dropout voltage of 300 mV at 1 A load. The device includes reverse current protection, logic-controlled shutdown consuming less than 1 μA, and internal current and thermal limits. It is stabilized by a 1 μF ceramic capacitor and functions across a temperature range of -40 °C to +125 °C.

Feature Summary

Reverse current protection prevents backflow when the output voltage exceeds the input voltage.
Logic-controlled enable pin allows for electronic shutdown with ultra-low standby consumption.
Internal current limit and thermal protection safeguard the device under fault conditions.

Applications

Low power battery-powered portable devices
Embedded systems requiring stable 1.0 V rail
Battery-operated handheld equipment

Procurement Notes

Verify the specific suffix PU10R against official datasheets to confirm the 1.0 V fixed output and SO8-batwing package. Ensure compatibility with 1 μF ceramic output capacitors as required for stability. Confirm availability status as distribution data may vary.

Selection Notes

Select this component for applications requiring a fixed 1.0 V supply with high efficiency and reverse current blocking. It is suitable where low quiescent current and compact surface-mount packaging are priorities. Verify that the load current does not exceed 1.2 A and input voltage remains within the specified 5.5 V maximum.

Part Context

This part belongs to the LDL112 family of low-dropout regulators designed for low-power applications. The family offers various fixed voltages and adjustable options in packages including DFN6 and SO8. The LDL112 series is characterized by its ability to drive 1.2 A with minimal voltage drop and enhanced protection features.
