Overview
The LDI8233-05EN is a fixed linear voltage regulator from Diotec Semiconductor, providing a nominal output of 5 V with a tolerance of ±1%. It supports an input voltage range of 4.5 V to 40 V and delivers up to 100 mA of output current. The device features a dropout voltage of 1.2 V at full load and maintains a typical power supply rejection ratio (PSRR) of 45 dB. Operating within a temperature range of -40 °C to +125 °C, it utilizes a SOT-23-5 surface-mount package.
Feature Summary
- Provides stable regulated output in low-dropout configurations
- Ensures high noise immunity through effective ripple suppression
- Supports operation across extended industrial temperature ranges
Applications
- Battery-powered portable electronic devices
- General-purpose logic circuit power supplies
- Sensor interface modules requiring stable bias voltages
Procurement Notes
Verify the specific suffix EN against official Diotec documentation to confirm pinout compatibility and thermal characteristics. Ensure the selected component meets the required input voltage headroom for your specific application design. Cross-reference datasheet parameters such as dropout voltage and maximum junction temperature to validate suitability for your operating conditions.
Selection Notes
Select this component when a fixed 5 V rail is required from higher input sources up to 40 V. The SOT-23-5 package offers space efficiency for compact designs. Consider the 100 mA current limit and 1.2 V dropout voltage when designing the power stage. Verify that the ambient temperature remains within the specified -40 °C to +125 °C operational range for reliable performance.
Part Context
This part belongs to the LDI8233 series of low-dropout regulators manufactured by Diotec Semiconductor. The series includes variants with different output voltages and packages, such as the LDI8233-05U in SOT-89-3. These regulators are designed for efficient power management in consumer and industrial electronics where stable voltage regulation is critical.
Replacement Considerations
The LDI8233-05U shares similar electrical specifications but uses an SOT-89-3 package, requiring PCB layout adjustments. The LDI8233-05EN is the direct equivalent in the SOT-23-5 form factor. Verify pin compatibility and thermal dissipation requirements before substituting.
