Overview

The MIC5205-5.0YM5-TR is a high-performance 150mA low-dropout linear regulator designed for low-noise and ultra-low quiescent current applications. It features a fixed 5V output and is housed in a compact SOT-23-5 package, making it suitable for battery-powered handheld electronics. The device includes a logic-controlled enable pin and internal protection against thermal overload, overcurrent, and reverse polarity.

Why Choose This Part

This LDO offers an excellent PSRR of 75dB at 100Hz and ultra-low noise output performance. Engineers benefit from integrated reverse-battery protection and a very low shutdown current of 5uA, which minimizes standby power consumption. The SOT-23-5 footprint provides a 150mA output capability while maintaining a small PCB area.

Applications

Battery-Powered Handheld Devices
Ideal for portable equipment where low quiescent current is critical for extending battery life.
RF and Wireless Modules
Provides clean, ultra-low noise 5V rails necessary for sensitive transceiver and receiver circuits.
Post-Regulation for Switching Supplies
Used to filter high-frequency noise from DC-DC converters to provide a stable analog supply.
Industrial Instrumentation
Provides precision 5V power with tight line and load regulation in space-constrained sensor housings.

Getting Started

Ensure that a high-quality ceramic bypass capacitor is placed close to the output pin to maintain stability and low-noise performance. Use the enable pin to toggle the regulator state; if the feature is not required, tie the pin directly to the input voltage. Review the thermal dissipation limits of the SOT-23 package to ensure the junction temperature stays within the -40C to 125C range under full load.
