Overview
The LDL112PVR is a low-dropout linear regulator from STMicroelectronics, housed in a DFN-6 surface-mount package. It delivers a maximum output current of 1.2 A with an adjustable output voltage range spanning from 800 mV to 5 V. The device operates within an input voltage window of 1.6 V to 5.5 V and maintains a typical dropout voltage of 350 mV. Quiescent current is specified at 240 uA, while the shutdown mode consumes less than 1 μA. It features a typical power supply rejection ratio of 53 dB and functions reliably across a temperature range of -40 °C to +125 °C.
Feature Summary
- Reverse current protection prevents backflow when input voltage drops below output voltage.
- Logic-controlled enable pin allows for electronic shutdown with ultra-low standby consumption.
- Stabilized for use with small ceramic output capacitors, simplifying board layout.
- Integrated thermal and current limiting safeguards against overload conditions.
Applications
- Low-power battery-powered portable devices
- Embedded systems requiring efficient voltage regulation
- Applications necessitating reverse current isolation
Procurement Notes
Verify the specific suffix 'PVR' corresponds to the required tape-and-reel packaging configuration and ensure the adjustable output variant matches the design requirements. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement orders.
Selection Notes
Select this component when designing circuits that require high efficiency under light loads due to its low quiescent current. The adjustable output capability provides flexibility for various logic levels, while the reverse current protection feature is critical for systems where input sources may be disconnected or shorted.
Part Context
This part belongs to the LDL112 series of low-dropout regulators designed for high-current applications. The series emphasizes low noise and stability with ceramic capacitors, targeting modern portable electronics where space and power efficiency are paramount constraints.
Replacement Considerations
Consult official substitution lists for compatible LDOs with similar current ratings and package footprints. Verify electrical compatibility regarding dropout voltage and quiescent current before implementing any alternative components.
