The HT7733C is an integrated DC-DC converter Step-Up fixed voltage regulator circuit in a SOT23-5 RoHS package manufactured by Holtek. The HT7733C provides an output voltage of 1.0V, 5V, and 3.3V, and is ideal for LOW ESR power-supply applications. This allows the HT7733C to be used with a wide range of systems, including portable devices, mobile handsets, and cameras. The HT7733C is a low-dropout/low-voltage device, and is capable of maintaining its output voltage even with input voltages as low as 0.85V. The device is designed with high accuracy, low power consumption, and excellent line and load regulation. In addition, the HT7733C provides a high level of protection features such as Thermal Shutdown Protection (TSP) and Short Circuit Protection (SCP). The HT7733C is RoHS compliant and is an excellent choice for a variety of digital circuits.
