Description
General part information
TPS7B81 Series
The TPS7B81 is a low-dropout (LDO) linear regulator that operates from input voltages up to 40 V and can supply up to 150 mA in current. With only 2.7 µA of quiescent current at light loads, the device is an excellent choice for wide input supply designs and high cell count battery applications that need very low standby power consumption. The 45-V transient tolerance provides additional headroom for applications where inductive kickback may be present, thereby reducing external circuitry for voltage suppression.
With integrated short-circuit and overcurrent limiting, the TPS7B81 protects the system during fault conditions. In addition to the low standby power consumption, the very low dropout voltage in light load conditions helps maintain regulation even when powered by depleted batteries.
The TPS7B81 is available in thermally enhanced, 8-pin HVSSOP and 6-pin WSON packages. Both packages offer high thermal conductivity, and their small size supports compact design, making them well suited for space-limited applications such as power tools or motor drive modules and battery packs.
