9.2.12 Low Battery Disconnect
In Figure 54, a band-gap voltage reference LM385 is used to generate shutdown signal, when Vin< 5.5 V, the LP2951 turns off and turns on again when VIN> 6 V.
For values shown, regulator shuts down when Vin< 5.5 V and turns on again at 6 V. Current drain in disconnected mode is approximately 150 µA.
