BA10T

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

The BA10T is a fixed positive output low drop-out voltage regulator from the BAOOT/FP series by Rohm Semiconductor. It provides a nominal 10V output with a maximum current capacity of 1A. The device operates within an input voltage range of 11V to 25V and features a typical dropout voltage of 0.3V at 0.2A load. Electrical characteristics include a ripple rejection ratio of 55dB, load regulation of 50mV, and an output voltage accuracy of ±5% (9.5V to 10.5V). It incorporates built-in overvoltage, overcurrent, and thermal shutdown protection circuits.

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

• Built-in overvoltage protection circuit prevents damage from excessive input voltage.
• Integrated overcurrent protection limits output current to prevent IC destruction during short circuits.
• Thermal shutdown circuit automatically turns off outputs when junction temperature exceeds safe limits.
• Low minimum input-output voltage differential enables efficient operation with minimal voltage headroom.
