BCT2040
1A Low Dropout Linear Regulators
GENERAL DESCRIPTION
The BCT2040 series low-power, low-noise, low-dropout, CMOS linear voltage regulators operate from a 2.2V to 6.0V input voltage. They are the perfect choice for low voltage, low power applications. A low ground current makes this part attractive for battery operated power systems. The BCT2040 series also offer ultra-low dropout voltage to prolong battery life in portable electronics. Output current minimum limit is 1A, and over-current protection limit is set at 2A typical.
These devices feature a shutdown function and are offered in active low with auto discharge. The output voltage is preset to voltages in the range of 1.0V to 5.0V. Other features include a low shutdown current, fold-back current limit and thermal shutdown protection.
The BCT2040 is available in Green ESOP-8 packages. It operates over an ambient temperature range of -40°C to +85°C.
