# MIC5209-1.8YM (Component)
## Description
Linear Voltage Regulators (LDO)
MIC5209-1.8YM
SOIC-8_L4.9-W3.9-P1.27-LS6.0-BL
LCSC Part Number: C150786
Microchip MIC5209 – 500 mA low-noise Low Dropout (LDO) linear voltage regulator designed for battery-powered and noise-sensitive applications. Supports input voltages from 1.8 V to 15 V and provides highly accurate regulated output with low dropout voltage and excellent line/load regulation. Features current limiting, thermal shutdown, reverse-battery protection, low quiescent current, and stable operation with minimal external components. Available in fixed and adjustable output versions for portable electronics, embedded systems, RF circuits, sensors, and post-regulation of switching power supplies.
