BCT2021
Low Power, Low Dropout, RF-Linear Regulators
GENERAL DESCRIPTION
The BCT2021 series are low power, High PSRR，Fast Response CMOS linear voltage regulators. The BCT2021 is optimized for wide variety of applications by supporting an input voltage range from 1.6V to 6V.This device features an internal soft-start to lower the inrush current which provides a controlled voltage to the load and minimizes the input voltage drop during start up. PSRR.
Other features include a shutdown mode, current limit, Foldback current Limit and thermal shutdown protection.
The BCT2021 is available in Green SOT23-3 SOT23-5, SC70-5 and UTDFN1x1-4L packages. It operates over an ambient temperature range of -40°C to +85°C.
