Microchip MIC5205-3.3YM5 3.3V 150mA LDO Voltage Regulator

Microchip MIC5205-3.3YM5 3.3V 150mA LDO Voltage Regulator is a fixed 3.3 V output low dropout (LDO) voltage regulator supplying up to 150 mA. Housed in a compact 5-pin SOT-23 package, it is designed for efficient and reliable operation in modern electronic designs.

Overview

The MIC5205-3.3YM5 offers a dropout voltage of just 165 mV at the full 150 mA output, which helps maximise usable battery life. It accepts input voltages from 2.5 V up to 16 V and provides an ultra-low noise output, very low ground current and an initial accuracy of better than 1%. These characteristics make it well suited to sensitive analogue and digital circuits in portable, battery-powered equipment.

Key Features

• Logic-controlled electronic enable (EN) pin, compatible with both CMOS and TTL levels, for external power management
• Quiescent current drops nearly to zero when disabled, reducing power drain during standby
• Very low dropout voltage and ground current, which increases only slightly in dropout conditions
• Extremely tight load and line regulation with a very low temperature coefficient for a stable 3.3 V supply
• Reversed battery protection, current limiting and overtemperature shutdown
• Dedicated reference bypass pin to further improve noise performance
• Specified for a junction temperature range from -40°C to +125°C

Applications

The regulator is suitable for portable, battery-powered applications such as handheld medical devices, IoT sensors and consumer electronics. It is also suitable for demanding RF and precision analogue applications where low noise is required.
