The OPTIREG™ linear TLS850F3TUV33 is a high performance, low drop out, fixed output voltage regulator in a PG-TO252-7 package. With an input voltage range of 3 V to 42 V and very low quiescent current of only 26 µA, this regulator is perfectly suitable for automotive systems or other supply systems connected to the battery permanently. The TLS850F3TUV33 provides an output voltage accuracy of ±2% and a maximum output current of 500 mA. The loop concept combines fast regulation and very good stability while requiring only one small ceramic capacitor of 1 µF at the output. Its operating range starts already at an input voltage of only 3 V (extended operating range), which makes the TLS850F3TUV33 also suitable to supply automotive systems that need to operate during cranking condition. The TLS850F3TUV33 has the Reset function to supervise the output voltage, including undervoltage reset and delay reset at power-on. It also includes an integrated Watchdog circuit with adjustable timing to monitor the microcontroller’s operation. A shared external delay capacitor sets both reset timing and watchdog timing. Internal protection features, such as output current limitation and overtemperature shutdown are implemented to protect the device against immediate damage due to failures like output short circuit to GND, overcurrent and overtemperature. This product is also available in version with 5 V output voltage: TLS850F3TUV50 Summary of Features Output voltage 3.3 V ±2% % current capability 500 mA Input voltage range from 3 V to 42 V Stable with 1 µF ceramic output capacitor Ultra low current consumption: typically 26 µA Very low drop out voltage: typically 100 mV at 100 mA Watchdog inhibit Programmable undervoltage reset threshold & delay time Separate outputs for reset and watchdog Output current limitation & Overtemperature shutdown Benefits Smaller input capacitors hence lower input filtering costs Suitable for cranking PCB space and cost savings Power saving for battery Potential Applications Automotive general ECUs Telematics systems ADAS cameras and radar systems Navigation systems Body control modules Family Overview For an overview of other available options in this family please click here.
