40V, 150mA TinyPower TM HT75Hxx
LDO with Protections Features General Description • Low power consumption The HT75Hxx series is a set of low power consumption
high voltage regulator implemented in a CMOS
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. • Low voltage drop
• Low temperature coefficient
• High input voltage (up to 40V)
• Output voltage accuracy: tolerance ±1.5%
• Soft start function 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. • Over current protection
• Over temperature protection
