Overview
The LDL112PV12R is a low-dropout linear regulator manufactured by STMicroelectronics, providing a fixed 1.2 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 thermal and current limiting. It is housed in a 6-DFN (3x3 mm) package and supports operation from -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 current consumption.
- Compatible with small ceramic output capacitors, facilitating compact circuit designs.
Applications
- Battery-powered portable devices requiring efficient power management
- Low noise analog circuits needing stable voltage regulation
- Embedded systems utilizing ceramic capacitor stabilization
Procurement Notes
Verify the specific suffix 'V12' confirms the 1.2 V fixed output configuration against the official datasheet. Ensure the 'R' suffix matches the required reel packaging format for your assembly line. Confirm RoHS compliance status and moisture sensitivity level requirements prior to ordering.
Selection Notes
Select this component when a fixed 1.2 V rail is required with high efficiency under light loads. The low quiescent current makes it suitable for battery-operated applications where standby power is critical. Verify that the input voltage remains above the minimum threshold while accounting for dropout voltage at peak load currents.
Part Context
This part belongs to the LDL112 family of low-dropout regulators designed for low-power applications. The series offers various fixed output voltages and adjustable options, sharing common features like reverse current protection and ceramic capacitor stability across different packages including DFN and SO-8.
Replacement Considerations
LDL112PV12 is the non-reel variant of the same electrical specification. Other LDL112 variants with different fixed output voltages or adjustable settings may serve as functional substitutes if voltage requirements differ.
