AP7370-50FDC-7

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

The AP7370-50FDC-7 is a positive voltage regulator IC from Diodes Incorporated, featuring a wide input voltage range of 3.2 V to 18 V and a fixed output voltage of 5.0 V. It provides a maximum output current of 300 mA with high accuracy (±1% for VOUT > 2.5V) and ultra-low quiescent current. The device incorporates reverse current protection, thermal shutdown, and short-circuit protection. It is housed in a U-DFN2020-6 (Type C) package.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Ultra-low quiescent current minimizes standby power consumption in battery-powered systems.
• Integrated reverse current protection prevents backflow when the input voltage drops below the output voltage.
• High output voltage accuracy ensures stable regulation across varying load and line conditions.
• Built-in thermal shutdown and current limit circuits protect the device under fault conditions.
