General Description  
The HT73XX series is a set of three-terminal, low power,  
high voltage regulators implemented in CMOS technol-  
ogy. The series features extremely low quiescent cur-  
rent which is typically 3.5mA . They allow input voltages  
as high as 12V. The device provides large current with a  
significantly small dropout voltage.  
The HT73XX consists of a high-precision voltage refer-  
ence, an error correction circuit, and a current limited  
output driver. They are available with several fixed out-  
put voltages ranging from 1.8V to 5.0V. CMOS technol-  
ogy ensures low dropout voltage and low current  
consumption. Although designed primarily as fixed volt-  
age regulators, these devices can be used with external  
components to generate variable voltages and currents.
