DI79L15DAB

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

The DI79L15DAB is a negative fixed voltage regulator from Diotec Semiconductor, housed in an SO-8 package. It provides a nominal output voltage of -15 V with a tolerance of ± 5%. The device supports an output current of 0.1 A and operates within an input voltage range of -30 V to -40 V. It functions reliably across a junction temperature range of -40 °C to +125 °C. Key electrical characteristics include a dropout voltage of 1.7 V, a quiescent current of 6 mA at maximum temperature, and ripple rejection of 39 dB at 120 Hz.

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

Verify the specific ordering suffix against official Diotec documentation to confirm compliance status. Standard versions lack automotive qualification, while suffixes like -Q indicate AEC-Q101 compliance. Confirm moisture sensitivity level (MSL 3) and soldering conditions (260°C/10s) match assembly requirements. Ensure the SO-8 package dimensions align with PCB layout constraints before finalizing procurement.

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

Select this component when a stable negative voltage rail is required for industrial or commercial circuits. The SO-8 package offers surface-mount convenience compared to through-hole alternatives. Consider the 1.7 V dropout voltage when designing input-output headroom. Verify that the 0.1 A output current meets load demands, as exceeding this limit may trigger internal protection mechanisms.

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

This part belongs to the DI79LxxDAB series of negative fixed voltage regulators. The series includes various output voltages ranging from -5.0 V to -24 V. All variants share identical mechanical data and protection features, differing only in their regulated output levels. The DI79L15DAB specifically targets applications requiring a -15 V supply rail.

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

Check for DI79L15D1 or DI79L15UAB if different packages are needed. Suffix variations such as -Q denote AEC-Q101 qualification. Verify pinout compatibility and thermal resistance values before substituting.
