BA15JC5T

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

The BA15JC5T is a fixed-output Low Dropout (LDO) regulator from Rohm Semiconductor, designed for applications requiring stable voltage regulation with high current capability. It delivers a maximum output current of 1.5A and features a fixed output voltage type with an accuracy of ±1.0% at 25°C. The device operates within an input voltage range of 3V to 16V, with a maximum withstand voltage of 18V. Key electrical parameters include a typical dropout voltage of 0.3V at 0.5A output, a ripple rejection of 55dB, and load regulation of 5mV across the full load range. It requires a 22µF output capacitor and functions within a junction temperature range of -40°C to 105°C.

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

• Integrated thermal shutdown and over-current protection circuits prevent damage during fault conditions such as short circuits or excessive loads.
• Low dropout voltage characteristic enables efficient operation even when the input-to-output voltage differential is minimal.
• High ripple rejection ratio ensures effective suppression of power supply noise, maintaining clean output voltage stability.

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

Verify the specific suffix and package variant against the official datasheet before ordering, as manufacturing status may indicate end-of-life or obsolescence phases. Confirm that the required output capacitor value and thermal management solutions align with the specified operating conditions. Ensure compatibility with existing board layouts given the TO220FP-3 package dimensions and pinout configuration.

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

Select this component when a fixed output voltage with ±1.0% precision is required alongside robust internal protection mechanisms. It is suitable for designs needing up to 1.5A continuous current with minimal external components. Consider the thermal dissipation requirements in the TO220FP-3 package and ensure adequate heatsinking if operating near maximum current limits or high ambient temperatures.
