TL75LPXXQ Datasheet, PDF (1/15 Pages) Texas Instruments – LOW-DROPOUT VOLTAGE REGULATORS

ą
• Very Low-Dropout Voltage . . . Less Than
400 mV at 300 mA
• Standby Mode Reduces Current to a
Maximum of 150 µA
• Output Regulated to Within ± 2% Over Full
Temperature Range
• Packaged in Thin Shrink Small-Outline
Package
• Only 10-µF Load Capacitor Required to
Maintain Regulation at I_O = 300 mA
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

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 T_J = −40°C to 125°C.
