The 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 5µA 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).
