HT73H44
Features - Low power consumption - Low voltage drop - Low temperature coefficient - High input voltage (up to 40V) - Output voltage accuracy: tolerance ±1.5% - Soft start function - Over current protection - Over temperature protection - Package types: 3-pin SOT89, 5-pin SOT23 Applications - Industrial/Automotive Application - Power Meter, Water Meter, Smart Meter - Portable/Battery-Powered Equipment General Description The HT73Hxx 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...
