The MIC5318-3.3YD5-TR is a high-performance, fixed 3.3V LDO from Microchip Technology, capable of delivering 300mA. It features an ultra-low dropout voltage of just 0.2V at full load and a very low quiescent current of 150µA. With excellent PSRR (75dB to 55dB), this regulator in a TSOT-23-5 package is ideal for noise-sensitive and battery-powered applications.
- Ultra-Low Dropout (0.2V @ 300mA): Maximizes efficiency by allowing operation with a very small input-to-output voltage difference.
- Very Low Quiescent Current (150µA): Significantly extends battery life in portable and standby applications.
- High PSRR (75dB to 55dB): Provides excellent noise rejection across a wide frequency range, ideal for RF and audio circuits.
- High Output Current (300mA): Supports a wider range of loads compared to standard 100mA LDOs.
Battery-Powered Portable Devices
With an ultra-low quiescent current of 150µA and a low dropout of 0.2V, it maximizes battery life in smartphones and wearables.
RF and Wireless Modules
Its excellent PSRR (75dB at 1kHz) ensures clean power for RF transceivers, reducing interference and improving signal integrity.
High-Performance Audio
The high PSRR across a wide frequency range (75dB to 55dB) minimizes power supply noise in audio codecs and amplifiers.
FPGA and DSP Core Supplies
Provides a stable 3.3V rail for digital cores, handling up to 300mA with minimal voltage droop.
Precision Analog Circuits
Ideal for powering op-amps and ADCs where a low-noise, well-regulated supply is essential for accuracy.
Always-On Domains
The low quiescent current makes it perfect for always-on power domains in IoT devices, preserving standby power.
