BA50BC0WT

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

The BA50BC0WT is a fixed-output low-dropout (LDO) voltage regulator manufactured by Rohm Semiconductor. It provides a stable 5V output with a maximum current capacity of 1A and an accuracy of ±2% at 25°C. The device operates within an input voltage range of 7V to 16V, with a maximum withstand voltage of 18V. Key electrical characteristics include a typical dropout voltage of 0.3V at 0.2A load, a circuit current of 0.5mA, and ripple rejection of 55dB. It requires a 22µF output capacitor and functions across a temperature range of -40°C to 105°C.

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

Verify the specific suffix and package configuration when ordering, as the BA50BC0WT series includes variants such as the FP and WT packages. Confirm that the fixed 5V output matches the system requirement, as other voltages are available in the same family. Ensure compatibility with the required TO220FP-5 mounting style and check for any end-of-life notices associated with this specific part number before finalizing procurement plans.

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

Select the BA50BC0WT when a robust 1A LDO with integrated protection features is required. Its low dropout voltage makes it suitable for applications where the input voltage is close to the desired output. The inclusion of both thermal and overcurrent protection reduces the need for external safety components. Consider the TO220FP-5 package for adequate heat dissipation in high-load scenarios compared to smaller surface-mount alternatives.

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

This component belongs to the BAxxBC0 series of 1A variable/fixed output LDO regulators from Rohm. The series is characterized by low saturation voltage and high reliability. The BA50BC0WT specifically denotes the fixed 5V version housed in a TO220FP-5 package. It shares core architectural features with other members like the BA33BC0WT and BA25BC0WT, differing primarily in output voltage and specific pinout configurations for the shutdown function.

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

Direct substitutes within the same family include BA50BC0FP (TO252-3 package) or BA50BC0T (SOT-89 package). For different output voltages, consider BA33BC0WT (3.3V) or BA25BC0WT (2.5V). Ensure the replacement maintains the 1A current rating and compatible thermal management requirements.
