BA12T

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

The BA12T is a fixed positive output linear voltage regulator manufactured by Rohm Semiconductor. It provides a stable 12V output with a maximum current capacity of 1A. The device features a low saturation voltage design, allowing for efficient regulation from fluctuating DC input sources. It operates within an input voltage range up to 25V and supports a junction temperature range from -40°C to 85°C. The component includes built-in protection circuits for overcurrent, thermal shutdown, and overvoltage conditions. It is housed in a TO-220FP through-hole package, suitable for applications requiring robust power management and thermal performance.

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

Verify the specific ordering suffix and package variant (TO-220FP) against the official Rohm datasheet to ensure compatibility with your PCB footprint and thermal requirements. Confirm that the fixed 12V output aligns with your system's voltage specifications. Check for any recent updates to the product status or recommended replacement parts directly from the manufacturer's documentation before finalizing procurement.

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

Select the BA12T when a fixed 12V output at up to 1A is required with integrated protection features. Its low dropout characteristic makes it suitable for inputs close to the output voltage. Ensure the thermal environment stays within the specified -40°C to 85°C operating range. Consider the TO-220FP package for adequate heat dissipation in high-current scenarios compared to smaller surface-mount alternatives.

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

The BA12T belongs to Rohm's BAOOT/BAOOFP series of low saturation voltage type 3-pin regulators. This series offers multiple fixed output voltages including 3V, 5V, 9V, and 15V, all supporting up to 1A output current. The family is designed to be compatible with the widely used BA17800 series, facilitating easier upgrades or replacements in existing designs while providing enhanced protection features.
