Description
L5150GJ is a low dropout linear regulator with
microprocessor control functions such as power
on reset, low voltage reset, early warning, on/off
control. Typical quiescent current is 55 µA in very
low output current mode and enabled regulator. It
drops to 5 µA with not enabled regulator.
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.
