Summary of INFINEON OPTIREG™ TLS850C2TE V50 & V33 LINEAR VOLTAGE REGULATORS
Summary: The TLS850C2TE is an ultra-low quiescent linear regulator for always-on and automotive applications. It accepts 3–40 V input, provides a fixed 5 V output (also available as 3.3 V), delivers up to 500 mA, and features low dropout, reset supervision, and internal protections. It is stable with a 1 µF ceramic output capacitor and optimized for cranking and low-power systems.
Parts used in the TLS850C2TE Project:
- TLS850C2TE fixed 5 V linear voltage regulator (also available TLS850C2TE V33 for 3.3 V)
- Input supply (3 V to 40 V source, e.g., automotive battery)
- Output ceramic capacitor 1 µF
- PCB or mounting substrate for the regulator
- Optional input decoupling capacitor (recommended for stability in practice)
- Connections/wiring for GND and reset/output lines
With an input voltage range of 3 V to 40 V and very this regulator is perfectly suitable for automotive or other supply systems permanently connected to battery. The very low quiescent current of only 20 µA makes the TLS850C2TE particularly suitable for always-on applications. The reset feature supervises the output voltage, including under-voltage reset and delayed reset at power-on.
The ultra-low dropout makes the device suitable for automotive systems that need to operate during cranking condition.
The new loop concept combines fast regulation and very high stability while requiring only one small ceramic capacitor of 1 µF at the output.
Internal protection features such as output current limitation and over-temperature shutdown, protect the TLS850C2TE from immediate damage caused by failure such as output shorted to GND, overcurrent or over-temperature conditions.
This part is also available in version with 3.3V output Voltage : TLS850C2TE V33
