AP7366-33W5-7

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

The AP7366-33W5-7 is a fixed-output low-dropout linear regulator manufactured by Diodes Incorporated. It provides a stable 3.3V output with a maximum current capacity of 600mA. The device operates within an input voltage range of 2.2V to 6V and maintains a typical quiescent current of 60µA. It features high power supply rejection ratio (PSRR) of 75dB at 1kHz and fast transient response characteristics. The unit includes built-in current-limit, short-circuit protection, and thermal-shutdown circuitry for fault prevention. It is housed in a SOT-25-5 surface-mount package and supports an ambient operating temperature range from -40°C to +85°C.
