L5150CJ and L5150CS are low dropout linear regulators with microprocessor control functions such as power on reset, low voltage reset, early warning.

Typical quiescent current is 55 μA at very low output current.

On chip trimming results in high output voltage accuracy (±2%). Accuracy is kept over wide temperature range, line and load variation. Early warning circuit monitors the input voltage and compares it with an internal voltage reference.

Output voltage reset threshold can be adjusted down to 3.5 V by means of an external voltage divider.

The maximum input voltage is 40 V. The max output current is internally limited. Internal temperature protection disables the voltage regulator output. In addition, only low-value ceramic capacitor on output is required for stability.
