MIC5209-3.6YS-TR

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The MIC5209-3.6YS-TR is a fixed-output linear voltage regulator manufactured by Microchip Technology, providing a nominal 3.6V output with a maximum continuous current of 500mA across the full operating temperature range. It utilizes a SOT-223-3 surface-mount package and supports an input voltage range from +2.5V to +16V. The device features a maximum dropout voltage of 600mV at full load and maintains better than 1% output accuracy. Key electrical specifications include a typical ground pin current of 80µA at light loads and a power supply rejection ratio (PSRR) of 75dB at 120Hz.
