Texas Instruments UA78M33CDCYR 3.3V 500mA Linear Voltage Regulator SOT-223-4

The Texas Instruments UA78M33CDCYR is a fixed 3.3V, 500mA linear voltage regulator in a compact SOT-223-4 surface-mount package. It delivers a continuous output current of up to 500mA, making it suitable for powering a range of low to moderate-power circuits.

Overview

Designed for on-card regulation, the device is intended to reduce noise and distribution issues often associated with single-point regulation systems. It operates from a wide input voltage range of 5.3V to 25V, offering flexibility in circuit design.

Key Features

• Fixed 3.3V output voltage
• Maximum output current of 500mA
• Input voltage range of 5.3V to 25V
