TPS71257 : The TPS712xx family of low-dropout (LDO) voltage regulators is tailored to noise-sensitive and RF applications. 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 mF ceramic output capacitors and features very low dropout voltages (125 mV typical at 250 mA). Each regulator achieves fast start-up times (approximately 60 ms with a 0.001 mF bypass capacitor) while consuming very low quiescent current (300 mA typical with both outputs enabled). When the device is placed in standby mode, the supply current is reduced to less than 0.3 mA typical. Each regu.
