Supplier Device Package SC-70-5

The MAX8510EXK28-G104 from Analog Devices is a high-performance low-dropout linear regulator delivering a fixed 2.8V output. Capable of sourcing up to 120mA, this LDO features an ultra-low 90 µA quiescent current and excellent power supply rejection of 78dB at 1kHz. Housed in a compact SC-70-5 package, it is engineered for noise-sensitive and battery-powered applications where efficiency and clean power are critical.

  • Extended Battery Life: Ultra-low 90 µA quiescent current minimizes standby power draw, ideal for portable devices.
  • Clean Power Delivery: High PSRR (78dB at 1kHz) filters out input noise, ensuring stable operation for sensitive analog and RF circuits.
  • Space-Saving Design: The tiny SC-70-5 package fits high-density PCBs without compromising performance.
  • Low Dropout: Only 135mV dropout at full load maximizes efficiency by allowing operation close to the output voltage.

Portable Battery-Powered Devices

The low 90 µA quiescent current and 120mA output make it ideal for extending battery life in wearables, hearing aids, and remote sensors where every microamp matters.

RF and Wireless Modules

With PSRR of 78dB at 1kHz, this LDO provides clean, stable power to RF transceivers and wireless MCUs, minimizing noise-induced signal degradation.

Precision Analog Circuits

The high PSRR (54dB at 100kHz) ensures that switching noise from upstream DC-DC converters does not corrupt sensitive analog measurements in data acquisition systems.

Compact IoT Endpoints

The SC-70-5 package (2mm x 2.1mm) fits space-constrained designs for smart sensors, smart tags, and other IoT nodes requiring a regulated 2.8V rail.

Low-Noise Audio Codecs

The excellent ripple rejection across 1kHz-100kHz makes this regulator suitable for powering audio codecs and DACs in portable media players, preserving audio fidelity.

Always-On Domains

The ultra-low quiescent current supports always-on microcontroller domains in smart home devices, maintaining state while drawing minimal power from the battery.
