Analog Devices has introduced the ADPL42005, a new CMOS-based low-dropout (LDO) linear regulator designed for noise-sensitive and space-constrained power applications. This high-performance regulator supports an input voltage range of 4 V to 20 V and delivers up to 500 mA of output current, making it an excellent choice for precision analog, RF, and sensor circuits.
Key Features of the ADPL42005
- Low Noise Performance: Delivers ultra-low output noise of 32 μVRMS (fixed output), enhancing performance in sensitive analog environments.
- High PSRR: Provides 58 dB at 10 kHz (VOUT = 3.3 V), ensuring effective rejection of power supply disturbances.
- Wide Input Voltage Range: Operates efficiently over a 4V to 20V range.
- Flexible Output Options: Offers six fixed output voltages (1.5 V, 1.8 V, 2.5 V, 3 V, 3.3 V, 5 V) and an adjustable output from 1.22 V to VIN − VDO.
- Energy Efficiency: Features a low quiescent current of 900 μA (VIN = 10 V, at 500 mA load) and shutdown current below 40 μA.
- Compact and Versatile Packages: Available in 8-lead 3 mm × 3 mm LFCSP and 8-lead SOIC packages, ideal for compact board layouts.
- High Precision and Stability: Includes ±0.8% initial accuracy, foldback current limit, thermal shutdown, power-good indicator, and user-programmable UVLO/enable functionality.
Applications:
- Regulation of noise-sensitive applications: ADC, DAC circuits, precision amplifiers, high-frequency oscillators, clocks, and PLLs
- Communications and infrastructure
- Medical and healthcare
- Industrial and instrumentation
