STMicroelectronics' New Automotive Linear Voltage Regulator Preserves Battery Energy in Challenging Conditions

The TL99VR03 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 fault recovery.
