BA15BC0T

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

The BA15BC0T is a fixed-output Low Dropout (LDO) regulator from ROHM Semiconductor, designed for local power supply applications. It delivers a maximum output current of 1A with an output voltage accuracy of ±2.0% at 25°C. The device operates within an input voltage range of 3V to 16V and withstands up to 18V. Key electrical parameters include a typical dropout voltage of 0.3V at 0.2A output, a ripple rejection of 55dB, and load regulation of 35mV across the full load range. It requires a 22µF output capacitor and functions reliably within an operating temperature range of -40°C to 105°C.

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

Verify component authenticity through authorized distributors as the BA15BC0T is listed under End-of-Life status. Confirm package integrity for TO-220FP-3 housing. Check RoHS compliance documentation. Ensure application requirements match the fixed 1.5V output specification. Validate thermal management capabilities given the 1A current rating and TO-220FP thermal properties.

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

Select this component when a fixed 1.5V output at 1A is required with high accuracy. Consider the PNP topology for lower dropout performance compared to NPN alternatives. Evaluate thermal dissipation needs due to the linear regulation method. Verify that the 3V minimum input voltage aligns with system headroom requirements. Confirm compatibility with standard 22µF output capacitors for stability.

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

The BA15BC0T belongs to the BAxxBC0 series of secondary LDO regulators. This family provides 1A output current with ±2% voltage accuracy. Variants exist for different output voltages and packages, such as the BA15BC0WT and BA15BC0WFP. The series emphasizes robust protection features including overcurrent and thermal shutdown for reliable operation in demanding environments.

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

Direct substitutes within the same series include BA15BC0WT (TO-220FP variant) and BA15BC0WFP (TO-252-5 variant). Cross-model replacements require matching the 1.5V fixed output, 1A current rating, and TO-220FP-3 package dimensions. Verify equivalent protection features and thermal performance before substitution.
