BA05SFP-E2

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

The BA05SFP-E2 is a positive fixed-output linear voltage regulator (LDO) manufactured by ROHM Semiconductor. It provides a stable 5V output with a maximum continuous current of 1A. The device utilizes a TO-252-5 surface-mount package, suitable for space-constrained designs. Key electrical characteristics include a typical dropout voltage of 300mV at full load and high accuracy for the fixed output. It operates within an input voltage range of 4V to 25V and supports junction temperatures up to 125°C. Integrated protection features ensure reliability under fault conditions.

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

Verify the exact part number suffix against official ROHM documentation to confirm package type and temperature grade. Ensure compatibility with your board's thermal design, as the TO-252-5 package dissipates heat through the exposed pad. Cross-reference with authorized distributors to confirm availability and authenticity, avoiding unauthorized sources that may supply counterfeit components.

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

Select this component when a fixed 5V output is required with moderate current demands up to 1A. Consider the TO-252-5 package if surface-mount assembly is preferred over through-hole. Evaluate thermal management requirements based on the expected voltage drop and load current. This LDO is suitable for applications where low noise and simple external component count are priorities compared to switching regulators.

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

The BA05SFP-E2 belongs to ROHM's BA00 series of low-dropout regulators. This family offers various output voltages and current ratings in compact packages. The SFP variant specifically denotes the TO-252-5 package configuration.
