Low-dropout regulator integrates soft-start circuitry functions
STMicroelectronics’ L99VR03 300mA low-dropout (LDO) regulator provides resilient and efficient power, with a wide input-voltage range and very low quiescent current consumption, only 3.5µA at no load. The IC has an enable pin for turning the regulator off, which reduces the idle current to 800nA, and integrates soft-start circuitry to limit current during power-up and […]
Automotive LDO supports 48 V batteries with 3.0 V minimum voltage
ABLIC Inc. launched the S-19230/1 Series, an automotive voltage regulator IC that achieves 2.0µA operating current for 48V auxiliary battery applications.
