SGM2021 Low Power, Low Dropout, Linear Regulators

GENERAL DESCRIPTION

The SGM2021 series low-power, low-noise, low-dropout, CMOS linear voltage regulators operate from a 2.5V to 5.5V 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 SGM2021 series also offer low dropout voltage to prolong battery life in portable electronics.

The SGM2021 features include output current limit and thermal shutdown protection.

The SGM2021 is available in Green SOT-23-3 package. It operates over an ambient temperature range of -40 to +85.
