ADP7142ARDZ Product Details

LDO (Low Dropout) Linear Voltage Regulators, 5V Output, Analog Devices

The Analog Devices Low Dropout (LDO) Linear Regulators offer fast transient response, excellent line and load regulation, and they have a wide input voltage range.


  • Low noise: 11 μV rms independent of fixed output voltage
  • PSRR of 88 dB at 10 kHz, 68 dB at 100 kHz, 50 dB at 1 MHz, VOUT ≤ 5 V, VIN = 7 V
  • Input voltage range: 2.7 V to 40 V
  • Maximum output current: 200 mA
  • Initial accuracy: ±0.8%
  • Accuracy over line, load, and temperature
    • −1.2% to +1.5%, TJ = −40°C to +85°C
    • ±1.8%, TJ = −40°C to +125°C
  • Low dropout voltage: 200 mV (typical) at a 200 mA load, VOUT = 5 V
  • User programmable soft start (LFCSP and SOIC only)
  • Low quiescent current, IGND = 50 μA (typical) with no load
