MCHPMIC5501-3.0YM5-TR
Overview
The MIC5501-3.0YM5-TR is a compact, fixed-output low-dropout (LDO) regulator designed to provide a steady 3.0V supply from an input range of 2.5V to 5.5V. It supports up to 300mA of output current while maintaining a low quiescent current of 38uA, making it suitable for battery-powered applications. The device includes an integrated enable pin for power management and thermal/current-limit protection for improved system reliability.
Why Choose This Part
This regulator offers a balance of 300mA output capacity and low power consumption in a standard 5-pin SOT-23 package. It features integrated protection against over-temperature and over-current conditions, ensuring robust operation in demanding environments. Its high PSRR and low noise profile support sensitive analog signal chains even in noisy digital environments.
Applications
Key Specifications
Getting Started
When designing with the MIC5501-3.0YM5-TR, ensure that input and output capacitors (typically 1uF ceramic) are placed close to the pins to ensure stability and improve transient response. The EN pin must be driven high to enable the device; if not controlled by logic, it should be tied to the VIN rail. Consult the Microchip datasheet for thermal derating curves if operating at high ambient temperatures or near the 300mA limit.
