The HT72xx series of positive, linear regulators features low quiescent current (4mA typ.) with low dropout voltage, making them ideal for battery applications. The space-saving 3-pin SOT23 package is attractive for ″Pocket″ and ″Hand Held″ applications. The devices are capable of supplying 300mA of output current continuously. They are available with several fixed output voltages ranging from 1.8V to 5.0V. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain variable voltages and currents. These rugged devices have Thermal Shutdown and Current Limiting to prevent device failure under the ″Worst″ of operating conditions.
“Minimalist ESP-8266 temperature/humidity sensor/programmer. This is a Kicad design which uses a PCB USB connector and integrates an ESP-12 (or 07), CH330N USB controller, a small voltage regulator (HT7233), and a AHT-10 temperature/humidity sensor …
