HT75Hxx

40V, 150mA Low Power LDO with Protections

General Information

(HT75Hxx 5-pin SOT89 & 8-pin SOP-EP Package Restricted Products. Notification Date : 2024/12/17 Effective Date : 2025/03/17)

The HT75Hxx series is a set of low power consumption high voltage regulator implemented in a BCD technology, which ensures low voltage drop and low quiescent current. They allow input voltages as high as 40V. They are available with several fixed output voltages ranging from 2.1V to 5.0V.

The soft start function controls the output slew rate to prevent the overshooting phenomenon when power on. The enable pin, CE, accepts CMOS level as logic input. When CE goes low, a fast discharging path pulls output voltage low a via 300Ω resistor. The internally output over current protection prevents the HT75Hxx from being burned even if the output node shorts to ground. The over temperature protection ensures that the junction temperature will not exceed 150°C. The soft start function inhibits the output overshooting when power on.
