BA033LBSG-TR

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

The BA033LBSG-TR is a positive fixed linear voltage regulator IC from Rohm Semiconductor, delivering a stable 3.3 V output with a maximum current capacity of 150 mA. It operates within an input voltage range of 4 V to 15 V and features a typical dropout voltage of 0.28 V at full load. The device provides high precision with ±1% output accuracy at 25°C and includes built-in protection circuits for overcurrent and thermal shutdown. Designed for surface-mount applications, it utilizes the compact SMP5 package and supports an operating temperature range from -25°C to +85°C.

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

Verify the specific suffix TR indicates tape-and-reel packaging configuration. Confirm the SMP5 package variant matches your PCB footprint requirements. Ensure the -25°C to +85°C industrial temperature range aligns with your operational environment specifications before finalizing procurement orders.

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

Select this component when a fixed 3.3 V rail is required with minimal external circuitry. The 150 mA limit suits low-power logic loads rather than high-current drivers. Consider the SMP5 package constraints for thermal dissipation in dense assemblies compared to larger through-hole alternatives.

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

This part belongs to Rohm's BAxxLBSG series of super-mini package regulators. It serves as a compact alternative to traditional LDOs, offering similar electrical performance in a significantly reduced footprint. The series targets consumer electronics where board real estate is limited but reliable regulation is essential.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct pin-compatible substitutes may include other 3.3V LDOs in SMP5 packages from different manufacturers, provided they meet the 150mA current and 15V input voltage specifications. Verify thermal characteristics and protection feature parity before substitution.
