TPS71202MDRCTEP

双通道， 250 mA输出，超低噪声，高PSRR ，低压差线性稳压器 DUAL, 250-mA OUTPUT, ULTRA-LOW NOISE, HIGH PSRR, LOW-DROPOUT LINEAR REGULATOR

The TPS71202 low-dropout LDO voltage regulator is tailored to noise-sensitive and RF applications. It features dual 250-mA LDOs with ultra-low 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. The 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. The regulator exhibits approximately 32 µVrms 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, benefit from high PSRR, low noise, and fast line and load transient features. The TPS71202 is offered in a thin 3-mm × 3-mm SON package and is fully specified from –55°C to 125°C TJ.
