Supplier Device Package 4-WLCSP (0.95x1.03)

The ADP172ACBZ-1.5-R7 is a low dropout linear regulator from Analog Devices, providing a fixed 1.5V output at up to 300mA. It features an ultra-low 60µA quiescent current and high PSRR of 73dB at 1kHz, making it ideal for noise-sensitive portable applications. The 4-WLCSP package is one of the smallest available, perfect for miniaturized designs.

  • Ultra-Small Package: 4-WLCSP (0.95x1.03mm) enables miniaturized product designs.
  • Low Quiescent Current: 60µA maximizes battery life in portable devices.
  • High PSRR: 73dB at 1kHz ensures clean power for sensitive analog and RF circuits.
  • Fixed 1.5V Output: Ideal for low-voltage digital and analog ICs.
