Overview
The LDLN015PU15R is a fixed-output linear voltage regulator from STMicroelectronics, providing a stable 1.5 V output with a maximum current of 150 mA. It operates within an input voltage range of 2.1 V to 5.5 V and features ultra-low noise performance, delivering 6.3 µV RMS in the 10 Hz to 100 kHz band. The device includes logic-controlled shutdown for low standby consumption, internal thermal protection, and short-circuit limiting. It is housed in a compact DFN-6 package and supports ceramic capacitors.
Feature Summary
- Ultra-low noise operation suitable for sensitive analog loads
- Logic-controlled electronic shutdown for extended battery life
- Internal thermal and constant current limiting protections
Applications
- Powering precision Analog-to-Digital Converters (ADCs)
- Supplying Voltage-Controlled Oscillators (VCOs) in mobile devices
- Powering sensors in personal digital assistants
Procurement Notes
Verify the specific suffix 'PU15R' against official documentation to confirm the 1.5 V fixed output voltage and reel packaging configuration. Confirm RoHS compliance status and check the lifecycle status, as this component may be marked as Not Recommended for New Designs (NRND). Ensure the selected package matches the required PCB footprint.
Selection Notes
Select this regulator when powering noise-sensitive components such as RF circuits or high-resolution data converters. It is appropriate for applications requiring a clean power supply from a single-cell lithium-ion battery or similar low-voltage source. Consider the DFN-6 package size if board space is limited.
Part Context
This component belongs to the LDLN015 series of ultra-low noise linear regulators designed by STMicroelectronics. The series provides various fixed output voltages ranging from 0.8 V to 3.3 V with 100 mV steps. All variants share common features including high PSRR, low quiescent current, and compatibility with small ceramic output capacitors.
Replacement Considerations
Check for other suffixes within the LDLN015 family for different output voltages. Verify availability of alternative LDOs with similar noise specifications if this part is discontinued.
