BA33D15HFP-TR

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

The BA33D15HFP-TR is a dual low-dropout (LDO) voltage regulator IC manufactured by ROHM Semiconductor. It provides two independent positive fixed output voltages of 3.3V and 1.5V, each capable of delivering up to 500mA of output current. The device operates within an input voltage range of 2.0V to 6.0V and features a typical dropout voltage of 0.4V at full load. Packaged in the compact HRP-5 surface-mount format, it includes built-in protection mechanisms such as thermal shutdown and over-current protection to ensure reliable operation in space-constrained electronic designs.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Dual-channel architecture providing separate 3.3V and 1.5V regulated outputs from a single package
• Low dropout voltage characteristic enabling efficient power regulation with minimal input-output differential
• Integrated safety protections including thermal shutdown and over-current limiting for enhanced system reliability

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

• Portable battery-powered devices requiring multiple stable voltage rails
• Embedded systems needing compact dual-voltage regulation solutions
• Consumer electronics utilizing low-power microcontrollers and peripherals

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

Verify the specific suffix TR indicates tape-and-reel packaging when ordering. Confirm that the required output voltages match the fixed 3.3V and 1.5V configuration provided by this part number. Ensure the application input voltage remains within the specified operational range to maintain proper regulation and avoid triggering under-voltage lockout conditions.

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

Select this component when a design requires two distinct low-voltage rails in a minimal footprint. It is suitable for applications where input supply voltage is close to the desired output levels due to its low dropout特性. Consider the 500mA per channel limit to ensure the total load does not exceed the device's thermal capabilities without adequate PCB heat dissipation.

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

This part belongs to the BA33 series of dual LDO regulators from ROHM. It shares the HRP-5 package form factor with other variants in the family but is distinguished by its specific 3.3V/1.5V output combination. It serves as a power management solution for multi-rail systems where size and efficiency are critical constraints.

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

Check for pin-compatible alternatives within the same HRP-5 package if sourcing issues arise. Verify that substitute parts offer identical 3.3V and 1.5V outputs with comparable current ratings and dropout characteristics to maintain circuit performance.
