L5050SDTR

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The L5050SDTR is a dual isolated 5 V low dropout linear voltage regulator for automotive applications, manufactured by STMicroelectronics. It operates within a DC supply voltage range of 5.6 V to 40 V and delivers up to 2x50 mA of continuous load current per output. The device features a maximum dropout voltage of 500 mV and maintains high output voltage accuracy of ±2%. Quiescent current consumption is typically 50 µA when enabled and drops to 5 µA per output when disabled. It is housed in an SO-8 package.
