Texas Instruments introduced a precision power operational amplifier (op amp) which operates on supplies up to 100V and provides a high output current of ±50mA with a 150 mA short circuit limit. The OPA454 is unity-gain stable and can track fast moving signals since it has a slew rate of 10V/µs and gain-bandwidth product of 2.5 MHz. It features a single or dual supply of ±4V (8V) to±50V (100V).
Consuming what is presented as the lowest quiescent current in the industry at 500nA, the Texas Instruments' TPS780xx LDO also has a voltage select pin for designers to dynamically shift to a lower voltage level in a MSP430 microcontroller-based battery-powered design when the microprocessor is in sleep mode to cut power by as much as half. Stable with any output capacitor greater than 0.1µF
