Product Details
BA33BC0FP-E2 - 1 A 3.3 V Fixed-Output LDO Regulator
ROHM Semiconductor BA33BC0FP-E2 is a low-saturation, fixed 3.3 V linear regulator rated for up to 1 A and supplied in a TO-252-3 / DPAK-3 surface-mount package.
Electrical limits, pin assignments, package data, and lifecycle status were checked against ROHM's exact product record and controlled series data sheet.
Overview
BA33BC0FP-E2 provides a regulated 3.3 V rail from inputs up to 16 V. Its PNP pass element supports a typical 0.3 V input-to-output differential at 200 mA, while integrated overcurrent protection and thermal shutdown help protect the regulator under overload and excessive-temperature conditions.
Key Advantages
Low differential voltage
The typical 0.3 V differential at 200 mA reduces input headroom compared with standard linear regulators.
1 A output capability
Supports logic and embedded rails when junction temperature and package dissipation are kept within limits.
Fixed 3.3 V regulation
No external feedback divider is required, simplifying the power path and reducing component count.
Integrated protection
On-chip overcurrent limiting and thermal shutdown address common overload and overheating faults.
Feature Summary
Electrical
- Fixed 3.3 V output
- 1 A maximum output current
- ±2% output-voltage accuracy at 25°C
- 55 dB typical ripple rejection
Implementation
- Low-saturation PNP output stage
- No shutdown-control pin
- 22 µF to 1000 µF output-capacitor range
- TO-252-3 / DPAK-3 footprint
Package & Footprint
The exact ROHM package is TO252-3, reference code DPAK-3. ROHM lists typical body dimensions of 6.50 mm × 9.50 mm with a 2.50 mm maximum height. The catalog registration is TO-252-3, DPAK (2 Leads + Tab), SC-63.
- Use the ROHM TO-252-3 land pattern and orientation mark.
- Connect the exposed fin to ground as specified by ROHM.
- Provide copper area appropriate for heat spreading.
- Keep the input and output bypass loops short.
The registered JPG was verified locally and on the production host as a TO-252 / DPAK three-terminal representation.

Replacement Considerations
ROHM marks BA33BC0FP-E2 as Last Time Buy and states that product discontinuation has been announced. A substitute must be evaluated for a fixed 3.3 V output, at least 1 A capability, the same TO-252-3 pin and fin functions, input range, dropout, capacitor stability, protection behavior, thermal limits, and qualification requirements.
No unconditional internal substitute is linked because no exact replacement orderable part was verified through both ROHM-controlled replacement information and the product API.
Manufacturer Information
BA33BC0FP-E2 is manufactured by ROHM Semiconductor. The “-E2” orderable suffix identifies tape-and-reel packing; ROHM lists 2,000 devices per reel, RoHS compliance, and moisture-sensitivity level 1 for this product record.
The manufacturer currently classifies this exact orderable part as Last Time Buy.
Applications
Embedded controllers
Fixed 3.3 V rails for microcontrollers and associated logic circuits.
Industrial electronics
Local point-of-load regulation where the input remains within the specified range.
Consumer systems
Board-level conversion from an intermediate rail to 3.3 V.
Power-supply subsystems
Post-regulation when linear-regulator dissipation is acceptable.
Quality & Authenticity
Verify the complete BA33BC0FP-E2 marking, reel label, lot traceability, package condition, and handling history against purchasing documentation. MSL 1 does not remove the need for normal ESD control, dry packaging inspection, and process qualification.
FAQ
Is BA33BC0FP-E2 adjustable?
No. It is the fixed 3.3 V member of the BAxxBC0 family.
Does it include an enable pin?
No. The three-pin FP version has VCC, N.C., OUT, and a ground fin; it does not include the shutdown control used by some five-pin family members.
Can it supply 1 A continuously?
Only when input voltage, load, board copper, ambient temperature, airflow, and junction-temperature calculations keep dissipation within the package limit.
What output capacitor is required?
ROHM specifies 22 µF to 1000 µF. Capacitor characteristics across bias and temperature must be considered.
Engineering Notice
Design decisions must follow the current ROHM data sheet and product-change documentation. Recheck lifecycle status before committing a new design, and validate thermal performance, transient behavior, stability, and fault recovery on the intended PCB under worst-case operating conditions.
