具有使能功能的 250mA、双通道低压降稳压器 10-VSON -40 to 125
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 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 reduced to less than 0.3 µA typical. Each regulator exhibits approximately 32 µrms of output voltage noise with VOUT = 2.8 V and a 0.01 µF 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 × 3mm SON package and is fully specified from 40°C to +125°C TJ.
