6.4.1 Shutdown Mode

When enable pins (EN+, EN–) are low, both positive and negative outputs of LM27762 are disabled, and the device is in shutdown mode reducing the quiescent current to minimum level. In shutdown, the outputs of the LM27762 are pulled to ground (internal 50 kΩ between each OUT pin and ground).
