Linear & Switching Voltage Regulators

MIC5317-3.3YMT-TZ Description

The MIC5317-3.3YMT-TZ is a high-performance, fixed-output linear voltage regulator from Microchip Technology, designed to deliver a stable 3.3V output with a maximum input voltage of 6V and an output current capability of 150mA. This surface-mount device (4DFN package) is optimized for low-power applications, featuring a low quiescent current of 39 µA and a minimal dropout voltage of 0.31V @ 150mA, ensuring efficient power conversion even with tight input-to-output differentials. Its 80dB to 65dB PSRR (1kHz–10kHz) makes it ideal for noise-sensitive circuits, while integrated protection features like over-current and over-temperature safeguards enhance reliability.

MIC5317-3.3YMT-TZ Features

• Fixed 3.3V Output: Precision-regulated voltage for stable power delivery.
• Low Dropout (LDO): 0.31V @ 150mA maximizes efficiency in battery-operated systems.
• Ultra-Low Quiescent Current: 39 µA minimizes power waste in standby modes.
• High PSRR: 80dB @ 1kHz ensures clean output in noisy environments.
• Enable Control: Allows for power management via an external signal.
• Robust Protection: Over-current and over-temperature shutdown.
