Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for LM337D2TG
Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview
The LM337D2TG is a three-terminal adjustable negative voltage regulator manufactured by onsemi. It provides an output current exceeding 1.5 A with an adjustable output voltage range from -1.2 V to -37 V. The device operates within a junction temperature range of -40°C to +125°C and features internal thermal overload protection, short circuit current limiting, and safe area compensation. It utilizes a D2PAK surface mount package (Case 936) and is RoHS compliant.
Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary
- Adjustable output voltage ranging from -1.2 V to -37 V using only two external resistors
- Internal thermal overload protection and constant temperature short circuit current limiting
- Output transistor safe-area compensation for robust operation
- Floating operation capability suitable for high voltage applications

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes
Verify the specific suffix 'D2T' confirms the D2PAK surface mount package configuration. Confirm the 'G' suffix indicates Pb-Free and RoHS compliance status. Ensure the operating temperature range matches the required application environment, as the BD2T variant covers -40°C to +125°C while other variants may differ.
Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes
Select this component when a negative adjustable voltage source exceeding 1.5 A is required in a surface mount form factor. Consider the thermal resistance characteristics of the D2PAK package for heat dissipation requirements. Verify that the input-output voltage differential remains within the 40 Vdc maximum rating during operation.
Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context
This part belongs to the LM337 family of three-terminal adjustable negative voltage regulators. It serves as the surface mount equivalent to through-hole packages like the TO-220AB (T suffix). The D2PAK package allows for automated assembly processes while maintaining the performance characteristics of the standard LM337 series.
