BA33BC0WFP-E2

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

The BA33BC0WFP-E2 is a single-channel, fixed-output low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a nominal output voltage of 3.3V with a maximum continuous output current of 1A. The device operates within an input voltage range of 4.3V to 16V and features a typical dropout voltage of 0.3V at 0.2A load. Key electrical specifications include a ripple rejection ratio of 55dB, a line regulation of 35mV across the full load range, and a voltage accuracy of ±2.0% at 25°C. It utilizes a TO-252-5 (PPAK-5) surface-mount package and supports an operating temperature range from -40°C to +105°C.

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

Verify the specific suffix E2 against the manufacturer's latest documentation to confirm compliance with current environmental standards and material declarations. Confirm that the TO-252-5 package dimensions align with your PCB footprint requirements. Ensure input voltage constraints are respected to maintain optimal dropout performance and prevent thermal overload in high-dissipation scenarios.

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

Select this component when a fixed 3.3V output is required with moderate current capability up to 1A. The low dropout characteristic makes it suitable for applications where the input voltage is close to the desired output level. Consider the thermal management capabilities of the TO-252-5 package if operating near maximum current limits or elevated ambient temperatures.
