概述
Description
RT9013-33GU5 is a fixed 3.3 V low-dropout regulator (LDO) from Richtek (RT9013 family). It provides a stable 3.3 V output from a wide input range (roughly 2.5–6.0 V) with up to about 150 mA output current. The GU5 suffix indicates the SOT-23-5 package. Key features typically include low dropout, low quiescent current, an enable (EN) pin for power-down, and protection (overcurrent/thermal shutdown). It’s suitable for battery-powered and small portable electronics needing a clean 3.3 V rail. External components: a suitable input and output capacitor per datasheet to ensure stability. Common applications: microcontrollers, sensors, wireless modules, LCD drivers, and other 3.3 V rail needs. For exact electrical specs, pinout, and recommended capacitors, refer to the latest RT9013-33GU5 datasheet.

Pinout
- Pin count: 5 pins (SOT-23-5 package).
- Function: Fixed 3.3V low-dropout regulator with an enable input. Pinout (typical): 1 = EN, 2 = GND, 3 = VIN, 4 = VOUT, 5 = NC (no connect). EN enables/disables the regulator; VIN is the supply input; VOUT provides 3.3V.
