BA00BC0WFP-E2 Linear Voltage Regulator — Equivalent & Substitute Parts

Part Overview

The BA00BC0WFP-E2 is an active linear voltage regulator IC manufactured by Rohm Semiconductor, classified as a Power Management (PMIC) component. This positive adjustable regulator delivers 1A output current and operates across an input voltage range of up to 16V, with adjustable output voltage from 1.5V to 12V. The device is housed in a TO-252-5 (DPAK) surface mount package and includes integrated over-current and over-temperature protection features with enable control capability.

The BA00BC0WFP-E2 maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Finding equivalent substitute parts becomes necessary when addressing supply chain constraints, inventory availability, or application-specific performance requirements while maintaining functional and electrical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BA00BC0WFP-E2 is determined by the following critical parameters:

Output Configuration & Type: Both main and substitute parts must provide positive adjustable voltage regulation with a single output.

Voltage Specifications: Substitute parts must accommodate the input voltage requirement (maximum 16V) and provide an adjustable output voltage range that encompasses or exceeds the 1.5V to 12V specification of the main part.

Current Rating: The substitute must deliver equal or greater output current capacity. The BA00BC0WFP-E2 specifies 1A output; substitutes rated at 1A or higher are acceptable.

Package Compatibility: Both parts must use the TO-252-5 (DPAK) surface mount package to ensure direct PCB footprint compatibility without layout modifications.

Protection & Control Features: Substitute parts must include over-current and over-temperature protection, plus enable control functionality to match the feature set of the main part.

Compliance & Status: Both parts must maintain Active product status and RoHS3 compliance to ensure long-term availability and regulatory alignment.

The LD29150PTR from STMicroelectronics meets all substitution criteria and qualifies as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The LD29150PTR qualifies as a direct substitute for the BA00BC0WFP-E2 based on functional equivalence and compliance alignment. Both devices maintain Active product status, ROHS3 compliance, and unlimited moisture sensitivity ratings, ensuring regulatory continuity and long-term supply viability.

The LD29150PTR provides enhanced performance characteristics in several areas: output current capacity increases from 1A to 1.5A, power supply rejection ratio (PSRR) improves from 55dB to 75dB at 120Hz, and operating temperature range extends to 125°C (versus 105°C). The adjustable output voltage range of the LD29150PTR (1.23V to 13.3V) encompasses the BA00BC0WFP-E2 specification (1.5V to 12V), confirming voltage compatibility.

The LD29150PTR operates at a lower maximum input voltage (14V versus 16V). Applications requiring input voltages between 14V and 16V must remain on the BA00BC0WFP-E2. For all other input voltage scenarios within the 14V limit, the LD29150PTR provides equivalent or superior performance.

Both parts use identical TO-252-5 (DPAK) packaging, eliminating PCB layout modifications. Pin configuration and control features (Enable, Over-Current, Over-Temperature protection) remain consistent, supporting direct schematic and layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the LD29150PTR replace the BA00BC0WFP-E2 in all applications?

A: The LD29150PTR is functionally equivalent for applications where the input voltage does not exceed 14V. The BA00BC0WFP-E2 supports input voltages up to 16V, while the LD29150PTR maximum is 14V. Verify your circuit's maximum input voltage before substitution.

Q: Are the package footprints identical?

A: Yes. Both the BA00BC0WFP-E2 and LD29150PTR use the TO-252-5 (DPAK) surface mount package with identical pin configuration. No PCB layout modifications are required for substitution.

Q: What are the key differences in electrical performance?

A: The LD29150PTR provides higher output current (1.5A versus 1A), superior power supply rejection ratio (75dB versus 55dB at 120Hz), and an extended operating temperature range (-40°C to 125°C versus -40°C to 105°C). The adjustable output voltage range is also slightly wider (1.23V to 13.3V versus 1.5V to 12V).

Q: Do both parts include the same protection and control features?

A: Yes. Both devices include over-current protection, over-temperature protection, and enable control functionality. Feature parity ensures equivalent circuit behavior and control implementation.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the BA00BC0WFP-E2 and LD29150PTR maintain ROHS3 compliance with unlimited moisture sensitivity ratings (MSL 1), confirming regulatory alignment and long-term availability.

Q: What is the quiescent current difference, and does it matter?

A: The BA00BC0WFP-E2 draws 0.5 mA quiescent current, while the LD29150PTR draws 180 µA. The LD29150PTR's lower quiescent current reduces standby power consumption, which may benefit battery-powered or low-power applications.
