Description
The TPL8536Q series prises wide-input LDO products with an integrated watchdog timer, capable of delivering up to 300 m A. These devices can operate within a voltage range from 4 V to 42 V, with a maximum transient voltage of 45 V. Their ability to function reliably with a minimum voltage of 4 V makes them suitable for cold-crank and start-stop scenarios.
The TPL8536Q series offers 5-V and 3.3-V fixed output voltage options, with a maximum shutdown current of only 2 μA. When the watchdog function is disabled, these devices have a low typical quiescent current of just 6...
