Description

The TPS712xx family of low-dropout (LDO) voltage regulators is tailored to noise-sensitive and RF appli- cations. These products feature dual 250 mA LDOs with ultralow noise, high power-supply rejection ratio (PSRR), and fast transient and start-up response. Each regulator output is stable with low-cost 2.2 µF ceramic output capacitors and features very low dropout voltages (125 mV typical at 250 mA). Each regulator achieves fast start-up times (approximately 60 µs with a 0.001 µF bypass capacitor) while consuming very low quiescent current (300 µA typical with both outputs enabled). When the device is placed in standby mode, the supply current is re- duced to less than 0.
