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
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
active. Less that 150
µA is required when the unit
is disabled.
A concern in many new designs is conservation of
board space and overall reduction in equipment
size. The thin shrink small-outline package
(TSSOP) minimizes board area and reduces
component height. This package has a maximum height of less than 1.1 mm (compared to the 1.75 mm of a
standard 8-pin SO package) and dimensions of only 6.5 mm by 4.4 mm.
All low-dropout regulators require an external capacitor at the output to maintain regulation and stability. To
further reduce board area and cost, the TL75LPxx devices are designed to require a minimum capacitor of only
10
µF. This is 1/10 the typical value used by many other low-dropout regulators. To simplify the task of choosing
a suitable capacitor, TI has included in this datasheet a list of recommended capacitors for use with these
devices.
The TL75LPxxQ devices are characterized for operation over TJ = −40°C to 125°C.
