Description
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.
