L5050STR

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

The L5050STR is a single-output, 5 V low dropout linear voltage regulator in an SO-8 package. It operates within a DC supply voltage range of 5.6 V to 40 V and delivers up to 50 mA of continuous load current, with pulsed capability reaching 100 mA. The device maintains a precision output voltage tolerance of ±2% across the full operating temperature range of -40 °C to +150 °C. Quiescent current consumption is typically 50 µA when enabled and drops to 5 µA when disabled. Key electrical parameters include a maximum dropout voltage of 500 mV at 100 mA and internal protections against short circuits and overtemperature conditions.
