STMicroelectronics LDLN030
The LDLN030 is a 300 mA very low-dropout voltage regulator, able to work with an input voltage ranging from 1.6 V to 5.5 V. The typical dropout voltage at 300 mA load is 150 mV. The very low quiescent current, which is just 16 μA at no load, extends battery-life of applications requiring very long standby time.| Part No. | LDLN030 |
