Description
L5300GJ 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.
The maximum input voltage is 40 V. The
maximum 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 (equal or above 220 nF).
