TI Claims Lowest Quiescent Current, Ultra-Small LDO Linear Regulator
September 24, 2019
Texas Instruments introduced an ultra-low-power low-dropout (LDO) linear voltage regulator.
Texas Instruments introduced an ultra-low-power low-dropout (LDO) linear voltage regulator, presented as having the industry’s lowest quiescent current (IQ) of sub-25 nA – one-tenth that of competing ultra-small devices. The new regulator features low IQ control at light loads even in dropout conditions, with best-in-class transient response for faster wake-up.
Key features and benefits:
-The TPS7A02’s ultra-low IQ control at light loads allows engineers to at least double the battery life for applications using a standard battery chemistry, with a shutdown IQ of 3 nA.
-The TPS7A02 can settle in less than 5 µs for 1-to-50-mA load transients, up to half the time of legacy devices.
-The TPS7A02 automatically transitions from an IQ-saving, low-load state to a high-load, fast-transient state without the need for any external circuitry or components.
By implementing the TPS7A02 with devices such as MSP430 microcontrollers, the SimpleLink CC2642R MCU, the TLV8802 nanopower operational amplifier, or the TMP1075 low-power temperature sensor, engineers can further optimize battery life and performance in their systems.
