TAIWAN SEMICONDUCTOR 5V 500mA LDO Voltage Regulator, TO-220-3

The TAIWAN SEMICONDUCTOR 5V Fixed Ultra-Low-Dropout (ULDO) Linear Regulator is designed for a wide range of applications requiring stable and reliable power management. Delivering a nominal output of 5V with a maximum output current of 500mA, this device ensures consistent performance across various electronic circuits.

Key Features

• Quiescent current increases only slightly at dropout, which effectively prolongs battery life
• Very low ground current of 200µA typical
• Ultra-low dropout voltage: typically 60mV at light load and 600mV at 500mA
• Tight initial tolerance of 2% and extremely good line regulation of 0.05% typical
• Very low output temperature coefficient for enhanced stability

Protection and Reliability

Safety and durability are prioritised with integrated protective features. The output voltage is trimmed before assembly for enhanced accuracy. The device includes internal current limiting, thermal shutdown protection, input over-voltage protection up to 30V, and a transient peak voltage tolerance of 60V. It also withstands a -18V reverse peak voltage.

Physical Specifications

Supplied in a through-hole TO-220 package with 3 pins, the component measures 43 mm in height, 33 mm in width, and 15 mm in depth, and weighs just 2 grams. It operates reliably within a temperature range of -20°C to 85°C.
