STMicroelectronics STLQ020 200 mA ultra-low current LDO
The STLQ020 is a 200 mA low-dropout voltage regulator, able to work with an input voltage ranging from 2 V to 5.5 V
The STLQ020 is a 200 mA low-dropout voltage regulator, able to work with an input voltage ranging from 2 V to 5.5 V.
The typical dropout voltage at maximum load is 160 mV.
The ultra-low quiescent current, which is just 0.3 μA at no load, extends battery-life of applications requiring very long standby time.
Even though the device intrinsic consumption is ultra-low, STLQ020 is able to provide fast transient response and good PSRR performance, thanks to its adaptive biasing circuit. It also includes short-circuit constant-current limiting and thermal protection.
