ME6226 Power Management IC, CMOS Type Ultra-Low Power High-Speed LDO Linear Regulator, 1.0–3.6V Output, 300mA, SOT23-5 Package

The ME6226 is a Power Management IC implemented as a CMOS type ultra-low power Low Dropout (LDO) linear regulator, optimized for battery-powered and always-on applications. It supports a maximum input voltage of 6.5V and provides fixed output voltage options ranging from 1.0V to 3.6V.

Designed for ultra-low standby consumption, the ME6226 features an extremely low quiescent current of just 0.6µA, making it ideal for energy-critical systems. Despite its low power operation, it delivers up to 300mA output current with ±1% output accuracy and stable high-speed transient response.

Housed in a compact SOT23-5 package, the ME6226 is well suited for space-constrained designs requiring efficient and reliable linear regulation.
