The TPS7B81 is a low-dropout (LDO) linear regulator that operates from input voltages upto 40 V and can supply up to 150 mA in current. With only 2.7 µA of quiescent currentat light loads, the device is an excellent choice for wide input supply designs and high cell countbattery applications that need very low standby power consumption. The 45-V transient toleranceprovides additional headroom for applications where inductive kickback may be present, therebyreducing external circuitry for voltage suppression.
With integrated short-circuit and overcurrent limiting, the TPS7B81 protects the systemduring fault conditions. In addition to the low standby power consumption, the very low dropoutvoltage 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, makingthem well suited for space-limited applications such as power tools or motor drive modules andbattery packs.
