Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for BA178M12T

BA178M12T

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

The BA178M12T is a fixed-output three-terminal linear voltage regulator from the ROHM BA178M series, designed to provide stable DC voltage from unregulated inputs. It delivers a nominal output of 12V with a maximum continuous current capacity of 0.5A. The device utilizes a TO-252-3 surface-mount package and operates within an ambient temperature range of -40°C to +85°C. Electrical specifications include a line regulation of up to 50mV and load regulation of up to 120mV under standard conditions.

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

Integrated overcurrent protection circuit limits output current to prevent IC damage during short circuits or overload conditions.
Built-in thermal shutdown circuit automatically turns off the output when junction temperature exceeds safe limits, preventing thermal destruction.
Features excellent ripple rejection characteristics for effective noise suppression in power supply applications.

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

Constant voltage power supplies for consumer electronics such as televisions
Power regulation circuits for audio equipment
General-purpose fixed voltage regulation in household appliances

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

Verify the specific suffix 'T' corresponds to the TO-252-3 surface mount package configuration as defined in the official ordering nomenclature. Confirm that the component meets RoHS compliance standards required for the target assembly process. Ensure the selected part number aligns with the 0.5A current rating variant distinct from the 1A BA178 series.

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

Select this component for applications requiring a fixed 12V output with moderate current demands up to 0.5A. Consider the TO-252-3 package for surface mount board space constraints. Evaluate thermal dissipation requirements based on the input-to-output voltage differential and ensure adequate heat sinking if operating near maximum power limits.
