Overview
The LDL112PV15R is a positive, fixed-output linear low-dropout regulator manufactured by STMicroelectronics. It provides a nominal output voltage of 1.5 V with a maximum continuous output current of 1.2 A. The device 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, with a maximum specified drop of 0.6 V at full load. Quiescent current is typically 70 µA, rising to a maximum of 400 µA during operation. Power supply rejection ratio (PSRR) is rated at 57 dB at 1 kHz. The component is housed in a 6-DFN (3x3 mm) package with a bare pad and supports surface-mount installation.
Feature Summary
- Integrated reverse current protection prevents backflow from output to input
- Logic-controlled enable pin allows for electronic shutdown with ultra-low standby consumption
- Internal circuitry includes thermal overload and current limit protection mechanisms
Applications
- Battery-powered portable devices requiring efficient power management
- Low noise analog circuits needing stable 1.5 V reference rails
- Embedded systems utilizing ceramic capacitor stabilization
Procurement Notes
Verify the specific suffix 'V15' confirms the fixed 1.5 V output variant. Confirm the 'R' suffix indicates reel packaging. Ensure the 6-DFN footprint matches the PCB layout. Check RoHS compliance status if required by local regulations. Validate that the operating temperature range meets system environmental requirements.
Selection Notes
Select this part when a fixed 1.5 V rail is required with high current capability. Consider the low quiescent current for battery life optimization. Verify input voltage headroom against the dropout characteristics. Ensure compatibility with ceramic output capacitors as per datasheet recommendations.
Part Context
This component belongs to the LDL112 family of low-dropout regulators designed for low-power applications. The series offers various fixed output voltages and adjustable options. It shares common features like reverse current protection and low IQ across the family. The DFN6 package provides a compact solution for space-constrained designs.
Replacement Considerations
LDL112PV18R: Fixed 1.8 V output variant in identical package. LDL112PV33R: Fixed 3.3 V output variant in identical package. LDL112PVR: Adjustable output version allowing custom voltage setting.
