Description

The TPS7A96 is an ultra-low noise (0.5 µV RMS), low-dropout (LDO) voltage regulator capable of sourcing 2 A with only 200 mV of dropout. The low dropout, in conjunction with a wide bandwidth error amplifier, allows for very high PSRR (104 dB at 1 kHz and 48 dB at 1 MHz) under low operating headroom (500 mV) and high output current (1.75 A). The device output is adjustable from 0.4 V to 5.5 V with an external resistor. With the wide input voltage range, the device supports operation as low as 1.9 V and up to 5.7 V. The device includes a programmable current limit, programmable PG threshold, and precision enable, allowing better control in the application. With the high-accuracy reference and wide-bandwidth topology, the device can be easily paralleled to achieve lower noise and higher current. With 1% output voltage accuracy (over line, load, and temperature) and soft-start capabilities to reduce inrush current, the device is designed for powering sensitive analog low-voltage devices.
