DI78L24DAB

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The DI78L24DAB is a positive fixed voltage linear regulator from Diotec Semiconductor, housed in an SO-8 surface-mount package. It provides a nominal output of 24 V with a maximum load current of 100 mA and a tolerance of ±5%. The device supports input voltages up to 40 V and operates within a junction temperature range of -40°C to +125°C. Internal protections include thermal overload shutdown and short-circuit limiting.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Integrated thermal overload protection for safe operation under high-temperature conditions
• Short-circuit protection capability ensures component safety during fault conditions
• Fixed voltage output eliminates the need for external feedback components

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Applications

• Active SCSI termination regulation
• Post-regulation for switch-mode DC-DC converters
• Battery-backed-up regulated power supplies

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific ordering suffix against official documentation before procurement. Standard versions are commercial/industrial grade; suffixes such as -Q or -AQ indicate AEC-Q101 compliance or qualification status. Confirm that the SO-8 package variant matches the intended PCB footprint and assembly requirements.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a stable 24 V rail is required at currents up to 100 mA. Ensure the input voltage does not exceed the 40 V absolute maximum rating. Consider the thermal resistance characteristics and ensure adequate copper pad area on the PCB to manage heat dissipation effectively within the specified operating temperature limits.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the DI78LxxDAB series of positive fixed voltage regulators manufactured by Diotec Semiconductor. The series offers various standard voltage outputs ranging from 3.3 V to 24 V, all sharing similar electrical characteristics and protection features while differing only in their regulated output levels.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Cross-reference with other manufacturers' 78L24 equivalents in SO-8 packages. Verify pinout compatibility and thermal performance metrics before substitution.
