Overview
The LDLN015PU10R is a low-dropout linear voltage regulator manufactured by STMicroelectronics. It provides a fixed output voltage of 1.0 V with a maximum output current of 150 mA. The device operates within an input voltage range of 2.1 V to 5.5 V and features a typical dropout voltage of 86 mV. Key electrical parameters include a quiescent current of 70 µA at full load, an ultra-low noise level of 6.3 µV RMS (10 Hz to 100 kHz), and high power supply rejection ratio exceeding 90 dB at low frequencies. It is housed in a DFN-6 package and supports operation from -40 °C to 125 °C.
Feature Summary
- Ultra-low noise performance suitable for sensitive analog loads
- High power supply rejection ratio for clean power delivery
- Logic-controlled shutdown mode for extended battery life
- Integrated thermal protection and short-circuit current limiting
Applications
- Powering analog-to-digital converters (ADCs)
- Supplying voltage-controlled oscillators (VCOs) in mobile devices
- Powering personal digital assistants (PDAs)
Procurement Notes
Verify the specific suffix 'PU10R' against the official datasheet to confirm the 1.0 V output voltage variant. Confirm the RoHS compliance status and check the lifecycle status, as availability may be limited due to potential obsolescence notices found in general product listings.
Selection Notes
Select this component when designing circuits requiring minimal output noise and high PSRR for sensitive signal chains. Ensure the input voltage remains within the 2.1 V to 5.5 V range and verify that the required load current does not exceed 150 mA. The DFN-6 package is suitable for space-constrained PCB layouts.
Part Context
This part belongs to the LDLN015 family of ultra-low noise linear regulators from STMicroelectronics. The family offers various fixed output voltages ranging from 0.8 V to 3.3 V in 100 mV steps, all sharing the same core architecture, package, and protection features while differing primarily in their regulated output voltage levels.
Replacement Considerations
Other members of the LDLN015 family with different output voltages may serve as functional replacements if the voltage requirement can be adjusted. Verify pin compatibility and ensure the alternative part meets the same noise and PSRR specifications.
