The HT7340-7 is an SOT-89 RoHS compliant low dropout regulator (LDO) manufactured by Holtek. The device is a high performance voltage regulator and provides a precise output voltage between 0.8V to 6.0V to meet the various needs of consumer and computer applications. It also offers a low dropout voltage of only 140mV at a full load current of 0.5A, which helps to reduce power consumption and improve system performance. Additionally, the LDO is designed with low noise features and a high PSRR, making it ideal for use in high-sensitive applications such as audio. Other features include a wide operating temperature range of -40°C to +125°C, thermal protection, and good ripple rejection properties.The device is suitable for battery powered tools, set-top boxes, game consoles, GPS systems, and other consumer electronics applications. It has a wide input voltage range of 3V to 28V and is available in a surface-mount package.
