G78MXX
Global Mixed-mode Technology
1A Positive Voltage Regulators
Features
General Description
Fixed Output
The G78MXX is a fixed positive output voltage regula-
tor with 4% accuracy, which operation voltage can be
up to 30V. The driving current can reach up to 1A with
enough headroom between input voltage and output
voltage. The typically quiescent current is about 4.2mA.
Internal current-limit protection and over temperature
protection are embedded to avoid unintentional dam-
aging during abnormal operation.
