The ET5H233S is a fixed 3.3V low dropout linear regulator from ETEK Microelectronics, offering 300mA output current in a compact SOT-23-3 package. Its ultra-low 4.5 µA quiescent current makes it ideal for battery-powered and always-on applications. With a dropout voltage of 1.3V at full load, it provides reliable regulation for a wide range of low-power electronics.
- Ultra-Low Quiescent Current: 4.5 µA extends battery life in standby and always-on applications.
- 300mA Output: Supports a wide range of low-power microcontrollers and sensors.
- Minimalist SOT-23-3: Only 3 pins simplify PCB layout and reduce component count.
- Stable 3.3V Rail: Fixed output ensures compatibility with standard 3.3V logic.
Coin-Cell Battery Devices
The ultra-low 4.5 µA quiescent current is perfect for coin-cell-powered devices like remote controls and key fobs, extending battery life to years.
Always-On Domains
In automotive and industrial systems, the ET5H233S maintains a 3.3V rail for always-on real-time clocks and memory, with minimal power draw.
Simple 3-Pin Replacements
The SOT-23-3 package offers a drop-in replacement for older 3-pin regulators, upgrading efficiency with lower quiescent current.
Low-Power Microcontrollers
