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 F ceramic output capacitors and features very low dropout voltages (125 mV typical at 250 mA). Each regulator achieves fast start-up times (approximately 60 s with a 0.001 F bypass capacitor) while consuming very low quiescent current (300 A typical with both outputs enabled). When the device is placed in standby mode, the supply current is reduced to less than 0.3 A typical. Each regulator exhibits approximately 32 Vrms of output voltage noise with VOUT = 2.8 V and a 0.01 F noise reduction (NR) capacitor. Applications with analog components that are noise-sensitive, such as portable RF electronics, will benefit from high PSRR, low noise, and fast line and load transient features. The TPS712 family is offered in a thin 3mm x 3mm SON package and is fully specified from -40C to +125C (TJ).
