The TC1303B-PI0EUN is a linear 0.88A low-dropout voltage regulator that has fast transient response for a wide range of input voltage and current in power supply designs. It has an active low-dropout voltage regulation to minimize heat dissipation and offer improved transient load characteristics. The TC1303B-PI0EUN has a wide input voltage range and can support both DC and AC input voltage.

Application Field

The TC1303B-PI0EUN is ideal for applications such as battery-powered devices, backup circuits, portable electronics, power supplies, PDAs and digital cameras where low-dropout regulation is needed. It is also used in multiple-output DC/DC converters where power is supplied to multiple devices from the same source.

Working Principle

The TC1303B-PI0EUN is a linear 0.88A low-dropout voltage regulator. It works on the principle of operation that a voltage is reference within the regulator to achieve a desired output voltage. This reference voltage is compared to the input voltage and the regulator adjusts the output voltage accordingly. The dropout voltage of the TC1303B-PI0EUN is below 0.5V at full load, allowing the regulator to operate with a minimum input voltage of only 1.5V. The TC1303B-PI0EUN has a current limit of 500mA, allowing it to function as both a voltage regulator and a current limiter.

Features

• Wide input voltage range
• Active low drop-out regulation
• Fast transient response
• Current limiting of 500mA
• Small SOT-23 package size

Conclusion

The TC1303B-PI0EUN linear 0.88A low-dropout voltage regulator is ideal for use in power supplies and multiple-output DC/DC converters. Due to its low-dropout voltage regulation, fast transient response and wide input voltage range, the TC1303B-PI0EUN is well suited for battery-powered devices, backup circuits, and other portable electronic devices.
