Texas Instruments Voltage Regulators - Linear LM3490IM5X-15

The LM3490IM5X-15 is a linear voltage regulator from Quarktwin Technology Ltd. designed to provide a fixed output voltage of 15V with a maximum load current of 100mA. It operates with an input voltage range of up to 30V and features a specified maximum dropout voltage of 1.2V at full load. The device is packaged in a compact 5-lead SOT-23 form factor, making it suitable for space-constrained applications. This regulator includes a logic-controlled ON/OFF feature, allowing for efficient power management in various subsystems. It is particularly useful as a post-regulator for switching DC/DC converters or as a bias supply for analog circuits. The output voltage tolerance is ±5% over the full load and temperature range, ensuring reliable performance in diverse operating conditions. The LM3490IM5X-15 is a viable alternative to traditional LM78LXX series regulators, especially in applications where lower dropout voltage is critical.
