Supplier Device Package SOT-23-6

The MAX6476UT15AD1-T is a 300mA low-dropout regulator from Analog Devices, providing a fixed 1.5V output. Housed in a standard SOT-23-6 package, it accepts inputs from 1.2V to 5.5V, making it versatile for mixed-voltage systems. With a low quiescent current of 136µA, it is optimized for battery-powered and energy-efficient designs. The device includes thermal overload and short-circuit protection for reliable operation.

  • Low Quiescent Current: 136µA extends battery life in standby modes.
  • Standard Package: SOT-23-6 is widely used and easy to assemble.
  • Wide Input Range: 1.2V to 5.5V supports multiple power sources.
  • 300mA Output: Sufficient for low-voltage digital cores and peripherals.

Low-Voltage Microcontroller Cores

Modern MCUs with 1.5V cores benefit from this LDO's 300mA capability, providing a stable supply from a 3.3V rail in IoT nodes.

FPGA Auxiliary Supplies

Low-power FPGAs often require 1.5V for auxiliary logic; this regulator delivers clean power with minimal quiescent draw.

Portable Audio Players

DACs and audio codecs running at 1.5V get a noise-free supply, with the SOT-23 package fitting compact media players.

Wireless Sensor Networks

With 136µA quiescent current, this LDO extends the life of battery-powered sensors that operate at 1.5V logic levels.

Embedded Systems with Mixed Voltages

When a system has 3.3V and 1.5V domains, this regulator provides the lower rail without needing a switching converter.

Battery-Powered Remote Controls

For low-power RF remotes using 1.5V MCUs, this LDO ensures stable operation from a 3V coin cell down to 1.2V.
