AP7370-33FDC-7

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

The AP7370-33FDC-7 is a positive voltage regulator IC from Diodes Incorporated, featuring a wide input voltage range up to 18V and a fixed output of 3.3V. It provides a maximum output current of 300mA with an ultra-low quiescent current of approximately 2.5µA. The device incorporates reverse current protection, thermal shutdown, and short-circuit protection. It operates within a junction temperature range of -40°C to +125°C and utilizes the U-DFN2020-6 (Type C) surface-mount package.

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

• Ultra-low quiescent current minimizes standby power consumption in low-power systems.
• Reverse current protection prevents battery discharge when input voltage drops below output voltage.
• Built-in thermal shutdown and short-circuit protection ensure operational safety under fault conditions.
