DI79M05D1

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

The DI79M05D1 is a negative fixed voltage linear regulator from Diotec Semiconductor, housed in a D-PAK (TO-252AA) package. It provides a nominal output voltage of -5.0 V with a tolerance of ±4%. The device supports an input voltage range up to -35 V and delivers a maximum output current of 500 mA. Key electrical parameters include a line regulation of 80 mV, load regulation of 100 mV, and ripple rejection of 60 dB at 120 Hz. The quiescent current is limited to 8.0 mA, and the dropout voltage is typically 1.1 V. It operates within a junction temperature range of -40°C to +150°C.

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

Verify that the specific part number matches the required negative voltage configuration and D-PAK package type. Confirm compliance with AEC-Q101 standards if automotive grade qualification is necessary, as standard versions differ from suffix -Q or -AQ variants. Ensure input voltage limits do not exceed -35 V during system operation.

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

Select this component when a stable negative rail is required for industrial or commercial circuits. The D-PAK package offers efficient thermal dissipation for currents up to 500 mA. Consider the 80 mV line regulation and 100 mV load regulation specifications for precision requirements. Verify ambient operating temperatures remain within the specified -40°C to +85°C range for reliable performance.
