HT75Hxx

40V, 150mA TinyPower^TMLDO with Protections

Features

General Description

• Low power consumption

• Low voltage drop

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

• Low temperature coeﬃcient

• High input voltage (up to 40V)

• Output voltage accuracy: tolerance ±1.5%

• Soft start function

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.

• 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
