BA50BC0WFP-E2

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

The BA50BC0WFP-E2 is a fixed-output low-dropout (LDO) linear regulator manufactured by ROHM Semiconductor. It provides a stable 5V output with a maximum current of 1A. The device operates within an input voltage range of 6V to 16V and features high accuracy of ±2.0% at 25°C. Key electrical characteristics include a typical dropout voltage of 0.3V at 0.2A load, 55dB ripple rejection, and 35mV load regulation from 0 to 1A. It incorporates thermal shutdown and overcurrent protection, operates between -40°C and 105°C, and utilizes a TO-252-3 surface-mount package.

• General-purpose voltage regulation in industrial control systems requiring stable 5V rails

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

Verify the specific suffix 'E2' to confirm RoHS compliance and lead-free status, as standard versions may differ. Ensure the ordering code matches the TO-252-3 package variant, distinct from tape-and-reel or cut-tape packaging options. Cross-reference the manufacturer's latest datasheet to confirm active status, as some BAxxBC0 series variants may be subject to production discontinuation notices.

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

Select this component when a fixed 5V output is required with 1A capacity and low dropout performance. It is suitable for applications where PNP-based LDOs offer better transient response than NPN types. Consider the TO-252-3 package for adequate thermal dissipation without requiring large heatsinks. Verify that the input voltage remains within the 6V-16V window to ensure proper regulation and avoid undervoltage lockout issues.
