ET5H233B is listed in the Voltage Regulators - Linear, Low Drop Out (LDO) Regulators range at ChipApex. The manufacturer field lists ETEK MICROELECTRONICS. Its product description is IC REG LINEAR 3.3V 300MA SOT89-3. Review the specifications below when checking this part for your BOM.
The ET5H233B is a high-input voltage, low-dropout linear regulator (LDO) manufactured by ETEK Microelectronics. It provides a fixed positive output with a maximum load current of 300mA. The device is characterized by ultra-low quiescent current consumption, making it suitable for battery-powered applications. It is available in surface-mount packages including SOT-23-5 and SOT-89-3L.
Verify the specific output voltage variant and package type (SOT-23-5 or SOT-89-3L) against the design schematic. Confirm that the input voltage range exceeds the maximum expected line voltage while remaining within the device's absolute maximum ratings. Ensure thermal dissipation requirements are met for the selected package under full load conditions.
Select this component when high input voltage compatibility and minimal standby current are critical. Compare the dropout voltage characteristics against system requirements to ensure stable regulation at minimum input voltages. Evaluate thermal performance based on the power dissipation calculated from the difference between input and output voltages multiplied by the load current.
This part belongs to the ET5H2XX series of LDOs from ETEK Microelectronics, designed for analog and power management solutions. The series targets mobile and consumer electronics markets requiring efficient power conversion with small form factors. ETEK focuses on high-performance analog integrated circuits for these sectors.
Check pin-to-pin compatible alternatives from the same manufacturer family. Verify that substitute parts maintain identical input voltage ranges and output current capabilities. Ensure thermal resistance values are comparable to prevent overheating in existing board layouts.
