NCP173 LDO Regulators

onsemi NCP173 LDO Regulators are CMOS low dropout devices designed for portable battery-powered applications that need ultra-low quiescent current and long operating life. These regulators support 150mA of output current, operate from a 2.2V to 5.5V input range, and feature a typical 500nA quiescent current to help extend battery runtime in space-constrained designs.
