MIC5202-3.3YM

MIC5202-3.3YM Description

The MIC5202-3.3YM from Microchip Technology is a dual-output, fixed-voltage linear regulator designed for precision power management in low-power electronic systems. This obsolete but reliable IC delivers two independent 3.3V outputs, each capable of supplying 100mA with a low dropout voltage of 0.35V @ 100mA. Its 26V maximum input voltage range and 1.5mA quiescent current make it suitable for battery-powered and noise-sensitive applications. Housed in an 8-pin SOIC package, the device integrates over-current, over-temperature, and reverse-polarity protection, ensuring robust operation in harsh environments.

MIC5202-3.3YM Features

• Dual Fixed Outputs: Two independent 3.3V regulators in a single package, reducing board space and BOM complexity.
• Low Dropout Voltage: 0.35V @ 100mA minimizes power dissipation, enhancing efficiency.
• Wide Input Range: Supports up to 26V, accommodating fluctuating power sources.
• Enable Control: Individual enable pins for each regulator allow dynamic power management.
• Protection Mechanisms: Includes over-current, over-temperature, and reverse-polarity safeguards.
• Low Quiescent Current: 1.5mA typical, ideal for battery-operated devices.
• RoHS3 Compliant: Meets environmental standards for lead-free manufacturing.

MIC5202-3.3YM Applications

The MIC5202-3.3YM excels in systems requiring stable, low-noise dual-voltage rails, such as:

• Portable Electronics: Powering microcontrollers, sensors, and wireless modules in handheld devices.
• Industrial Controls: Reliable voltage regulation for PLCs, motor drivers, and instrumentation.
• Automotive Systems: Auxiliary power for infotainment, telematics, and low-power ECUs.
• Embedded Systems: Dual-voltage supply for FPGAs, DSPs, and mixed-signal circuits.

Conclusion of MIC5202-3.3YM

While marked as obsolete, the MIC5202-3.3YM remains a viable choice for legacy designs or applications demanding dual 3.3V rails with robust protection and low dropout. Its integration of two regulators, enable control, and fault protection simplifies power architecture in space-constrained or noise-sensitive environments. Engineers seeking alternatives should verify availability but can leverage this IC’s proven performance in industrial, automotive, and portable systems.
