Holtek Semiconductor HT73L27
The HT73Lxx are a series of low dropout voltage regulators with an input voltage range from 2.3V to 6.6V. They are available in a range of fixed output voltages from 0.9V to 3.6V. When the CE pin input is low, a fast discharge path pulls the output voltage low via an internal pull-down resistor.| Part No. | HT73L27 |

GENERAL DESCRIPTION
An internal over-current protection circuit prevents the devices from damage even if their output was shorted to ground. An over-temperature protection circuit ensures the device junction temperature will not exceed a temperature of 150ºC. Due to the device’s outstanding PSRR and low output noise performance features, they are suitable for use in powering RF applications such as sub-1GHz transceivers.
