novoTon NCT3730S-L
NCT3730S/ S-L
1. GENERAL DESCRIPTION
The NCT3730S/S-L is a high performance positive voltage regulator designed for use in
applications requiring very low input voltage and very low dropout voltage at up to 3A(peak). It
operates with a VIN as low as 1.0V and control voltage 3V with output voltage programmable
as low as 0.8V. The significant feature includes ultra low dropout, ideal for applications where
VOUT is very close to VIN. Additionally, there is an enable pin to further reduce power
dissipation while shutdown. The NCT3730S/S-L provides excellent regulation over variations in
line, load and temperature, and provides a Power Good indicator to indicate if the voltage level
of output voltage reaches 90% of its rating value.
2. FEATURES
