BA178M20CP-E2

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

The BA178M20CP-E2 is a fixed positive linear voltage regulator from the ROHM BA178M series, housed in a TO-220CP-3 through-hole package. It provides a fixed output voltage of 20V with a maximum continuous output current of 0.5A. The device operates within an input voltage range of 23V to 33V and withstands a maximum voltage of 35V. Key electrical parameters include a circuit current of 4.5mA, line regulation of 8mV, load regulation of 20mV, and a typical power supply rejection ratio (PSRR) of 58dB. It functions reliably across an operating temperature range of -40°C to +85°C.

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

Verify the specific suffix E2 confirms RoHS compliance and lead-free status as per manufacturer documentation. Confirm the TO-220CP-3 package type matches your PCB footprint requirements. Ensure the fixed 20V output aligns with your system design needs. Check for any discontinuation notices or end-of-life notifications from ROHM Semiconductor before finalizing procurement plans.

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

Select this component when a robust 500mA linear regulator with integrated protection features is required. The TO-220CP-3 package offers high power dissipation capabilities suitable for applications where heat sinking may be necessary. Consider the 8mV line regulation and 58dB PSRR if noise sensitivity is a factor. Verify that the input voltage range of 23V to 33V accommodates your supply variations.

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

The BA178M20CP-E2 belongs to the BA178M series of linear regulators manufactured by ROHM Semiconductor. This series is designed for general-purpose applications requiring reliable voltage regulation. The part is distinct from surface-mount variants like the BA178M20FP, which uses a TO-252-3 package. The CP suffix indicates the through-hole TO-220 form factor, providing mechanical stability and ease of mounting for higher power applications.
