L5300AH7TR

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

The L5300AH7TR is a low dropout linear regulator with microprocessor control functions, including power-on reset and low-voltage reset. It features a fixed 5 V output with ±2% accuracy and supports up to 300 mA load current. The device operates within an input voltage range of 5.6 V to 40 V and maintains stability using only low-value ceramic capacitors (≥220 nF). Quiescent current is typically 60 μA at zero output current and drops to 10 μA in disable mode. It includes thermal shutdown, short-circuit protection, and an enable pin for power management.
