DUAL 250 MA OUTPUT, ULTRALOW-NOISE, HIGH PSRR, LOW-DROPOUT LINEAR REGULATOR

The TPS71157 low-dropout (LDO) voltage Regulator is tailored to noise-sensitive and RF applications. This product features 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 µ 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 µ s with a 0.001 µ F bypass capacitor) while consuming very low quiescent current (300 µ A typical with both outputs enabled). When the device is placed in standby mode, the supply current is reduced to less than 0.3 µ A typical. Each Regulator exhibits approximately 32 µ V RMS of output voltage noise with V OUT = 2.85 V and a 0.01 µ 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 TPS71157 is offered in a wafer-chip scale package and is fully specified from – 40 ° C to +125 ° C By Texas Instruments
