Overview
The LDLN015PU12R is a linear voltage regulator from STMicroelectronics providing a fixed 1.2V 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 a typical dropout voltage of 86 mV. The device exhibits ultra-low noise, specified at 6.3 µV RMS between 10 Hz and 100 kHz, and high power supply rejection ratio (PSRR) exceeding 90 dB at low frequencies. Quiescent current is typically 35 µA at no load and 70 µA at full load, with shutdown consumption below 1 µA. It includes logic-controlled electronic shutdown, short-circuit constant current limiting, and thermal protection, ensuring stability with ceramic capacitors.
Feature Summary
- Ultra-low noise performance suitable for sensitive analog loads
- Logic-controlled electronic shutdown for extended battery life
- Integrated short-circuit constant current limiting and thermal protection
Applications
- Powering analog-to-digital converters (ADC)
- Supplying voltage-controlled oscillators (VCO)
- Portable personal digital assistants (PDAs)
Procurement Notes
Verify the specific suffix PU12R against official datasheets to confirm the fixed 1.2V output voltage and DFN6 package configuration. Ensure compatibility with required ceramic output capacitance values as specified in the manufacturer's documentation to maintain stability.
Selection Notes
Select this component for applications requiring clean power supplies for noise-sensitive circuits. The wide input voltage range and low dropout characteristics make it suitable for battery-operated systems where efficiency and signal integrity are critical.
Part Context
This part belongs to the LDLN015 series of ultra-low noise linear regulators designed for portable electronics. The series offers various fixed output voltages and utilizes a compact DFN6 package to minimize PCB footprint while delivering high PSRR and low quiescent current.
Replacement Considerations
Check for other parts within the LDLN015 family offering different fixed output voltages if system requirements change. Verify pinout and package dimensions when considering alternative manufacturers' equivalents.
