Texas Instruments UA78M05CDCY 5V 500mA Linear Voltage Regulator SOT-223

The Texas Instruments UA78M05CDCY 5V 500mA Linear Voltage Regulator is a fixed 5V positive linear voltage regulator supplied in a compact SOT-223 surface-mount package. It delivers a stable 5V output from an input voltage range of 7V to 25V and supplies up to 500mA of continuous output current.

Overview

This 3-terminal regulator simplifies circuit design because it requires no external components for basic operation, which helps save board space. Internal protection features include thermal-overload shutdown and internal short-circuit current limiting, which help protect the device against overload conditions. The output transistor also includes safe-area compensation. An output capacitor is not required for stability, which reduces the number of components in the bill of materials.

Key Features

• Fixed 5V positive output
• Input voltage range of 7V to 25V
• Up to 500mA continuous output current
• Thermal-overload shutdown and internal short-circuit current limiting
• Safe-area compensation on the output transistor
• No output capacitor required for stability
• Manufactured with no antimony or brominated flame retardants (no Sb/Br)

Applications

The regulator is suited to on-card regulation, helping to reduce noise and distribution problems associated with single-point power supplies. With external components, it can be configured for adjustable output voltages and currents, or used as the power-pass element in a precision regulator circuit. Typical application areas include portable and battery-powered devices, computer systems and peripherals, communications and networking equipment, and general-purpose power supply regulation on PCBs.

Specifications

The device has an operating temperature range of 0°C to 125°C and offers high power-dissipation capability in a small footprint. Product dimensions are 3.3 (width) x 1.5 (depth) x 4.3 (height), and the product weighs 0.224 g.
