The OPTIREG™ linear TLS820F3ELV33 is a high performance, low drop out, fixed output voltage regulator in a PG-SSOP-14 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 TLS820F3ELV33 provides an output voltage accuracy of ±2% and a maximum output current of 200 mA. The loop concept combines fast regulation and very good stability while requiring only one small ceramic capacitor of 1 µF at the output. The operating range starts already at an input voltage of only 3 V (extended operating range). This makes the TLS820F3ELV33 also suitable to supply automotive systems that need to operate during cranking condition. The device can be switched on and off via Enable. The Reset supervises the output voltage, including undervoltage reset, delay reset at power-on and an adjustable lower reset threshold. An integrated Watchdog circuit with adjustable timing monitors 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: TLS820F3ELV50 Summary of Features Output voltage 3.3 V ±2% % current capability 200 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 Enable 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.
