General Description
The HT75xx-7 is a low power high voltage series of
regulators implemented in CMOS technology which
has the advantages of low voltage drop and low
quiescent current. They allow input voltages as high
as 30V and are available with several fixed output
voltages ranging from 2.1V to 12.0V.
When the CE input is low, a fast discharge path pulls
the output voltage low via an internal pull-down
resistor. An internal over-current protection circuit
prevents the device from damage even if the output
is shorted to ground. An over-temperature protection
circuit ensures the device junction temperature will
not exceed a temperature of 160°C.
