Applications
• Battery-powered equipment • Communication equipment • Audio/Video equipment
General Description
The HT75Rxx-7 series of devices are low-power high-voltage regulators implemented in CMOS technology, which ensures low voltage dropout and low quiescent current. They allow input voltages as high as 30V and are available with several fixed output voltages ranging from 3V to 12V. The devices include a soft start function, which is used to control the output slew rate to prevent the overshooting phenomenon when power on. The chip enable pin, CE, accepts a CMOS level as logic input. When the CE input is low, a fast discharge path pulls the output voltage low via a 300Ω resistor. An internal over current protection circuit prevents the devices from damage even if the output is shorted to ground. An over temperature protection circuit ensures that the device junction temperature will not exceed a temperature of 150°C. The soft start function inhibits the output overshooting when power on.
