The LY73XX series is a set of three-terminal, low power, high voltage regulators implemented in CMOS ogy. The series features extremely low quiescent cur-technol-rent which is typically 4uμA. They high as 12V. The device provides large current with aallow input voltages as significantly small dropout voltage.
The LY73XX consists of a high-precision voltage refer- ence, an error correction circuit, and a current limnited 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.
