Input-voltage range is from 2.7 V to 5.5 V, and output current goes up to ±250 mA. The device provides a small solution size with few external components. Negative voltage is generated by a regulated switched-capacitor voltage inverter followed by a low- noise negative LDO. The switched-capacitor voltage inverter of the LM27762 device operates at 2-MHz (typical) switching frequency to reduce output resistance and voltage ripple. Positive voltage is generated from the input by a low-noise positive LDO. With an operating current of only 390 µA and 0.5-µA typical shutdown current, the LM27762 provides ideal performance for power amplifier and DAC bias and other high-current, low-noise negative voltage needs. Positive and negative outputs of LM27762 have dedicated enable inputs. These outputs support independent timing for the positive and negative rails for specific system power-sequence needs. Enable inputs can be also shorted together and connected to the input voltage. The LM27762 has an optional Power Good feature.
