Overview
The Diotec Semiconductor LDI1117-05H is a fixed-output Low Dropout (LDO) linear voltage regulator housed in a SOT-223 surface-mount package. It provides a nominal output voltage of 5V with a maximum input voltage rating of 15V and supports an output current of 1A. The device features a typical dropout voltage of 1V at full load, with a maximum specified dropout of 1.25V. Key electrical characteristics include a line regulation of 6mV, load regulation of 10mV, and a typical power supply rejection ratio (PSRR) of 50dB. The component operates within a junction temperature range of -40°C to +150°C and includes internal protection against overcurrent and thermal overload.
Feature Summary
- Provides stable fixed 5V output for positive polarity applications
- Integrates overcurrent and thermal shutdown protection mechanisms
- Operates with low dropout voltage for efficient power management
- Delivers high ripple rejection for clean power supply lines
Applications
- General-purpose linear voltage regulation in electronic circuits
- Power management sections in embedded systems
- Biasing stages requiring stable 5V supply rails
- Interface circuits needing regulated power from higher voltage sources
Procurement Notes
Verify the specific suffix 'H' against official Diotec documentation to confirm package type and compliance status. Ensure the required output tolerance aligns with system specifications. Confirm moisture sensitivity level handling requirements during assembly. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before procurement.
Selection Notes
Select this component when a fixed 5V output is required from an input voltage up to 15V. The SOT-223 package suits applications needing moderate heat dissipation capabilities. Consider the 1A current limit and dropout characteristics relative to the minimum input voltage. Verify that the operating temperature range meets the environmental conditions of the target application.
