DI78L15DAB

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

The DI78L15DAB is a positive fixed voltage linear regulator from the DI7xxAB series by Diotec Semiconductor, housed in an SO-8 surface-mount package. It provides a nominal output voltage of 15 V with a tolerance of ±5%, supporting a maximum output current of 0.1 A (100 mA). The device operates within an input voltage range of up to 35 V and maintains functionality across a junction temperature range of -40°C to +125°C. Key electrical characteristics include a typical quiescent current of 6.5 mA at 25°C, a dropout voltage of 1.7 V, and a ripple rejection ratio of 39 dB at 120 Hz.

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

Verify component authenticity through authorized Diotec distributors or direct manufacturer channels. Confirm compliance with specific environmental standards such as RoHS and REACH requirements relevant to your region. Ensure proper handling procedures are followed due to moisture sensitivity classification level 3. Validate that the SO-8 package footprint matches your PCB design constraints before finalizing procurement orders.

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

Select this regulator when a stable 15 V output is required with moderate current demands up to 100 mA. Consider the 35 V maximum input rating for applications involving higher supply voltages. Evaluate thermal management needs based on the specified power dissipation limits and ambient operating temperatures ranging from -40°C to +125°C. Ensure adequate heatsinking or copper pad area on the PCB to maintain junction temperature within safe operational boundaries.
