description
The TL75LPxxQ devices are low-dropout
voltage regulators specifically targeted for use in portable applications. These devices generate fixed output
voltages at loads of up to 300 mA with only 400-mV dropout over the full temperature range.

Low-dropout
voltage regulators are commonly used in battery-powered systems such as analog
typical application schematic
and digital cellular phones. The TL75LPxx family of regulators feature a TTL/
CMOS-compatible enable terminal, which can be used to switch the device into standby mode. This feature reduces power consumption when the instrument is not
