Current detection-on-off control circuit and push-pull output LDO circuit

The invention provides a current detection-on-off control circuit and a push-pull output LDO circuit. A first connecting end of a reference current circuit is connected with a first connecting end of a P-type current detection-on-off control circuit, and a second connecting end of the reference current circuit is connected with a first connecting end of an N-type current detection-on-off control circuit; a first input end, a first output end and a second output end of the control circuit are formed on the P-type current detection-on-off control circuit, and a second input end, a third output end and a fourth output end of the control circuit are formed on the N-type current detection-on-off control circuit. According to the push-pull output LDO, the value of the output current or the input current is detected, the corresponding push-pull output circuit is automatically switched off or switched on, and the push-pull output LDO can be prevented from consuming too much quiescent current due to the fact that a PM
