UCC384DP-ADJG4

Стабилизатор с малым падением напряжения, регулируемый, -15В до -3.2В (Vin), 250мВ, -1.2В до -15В.

The UCC384DP-ADJG4 is a Negative Linear Pass Regulator tailored for low-dropout applications where low-quiescent power is important. Fabricated with a BCDMOS technology ideally suited for low input-to-output differential applications, the Dropout voltage decreases linearly with output current, so that dropout at 50mA is less than 20mV. Quiescent current consumption for the device under normal conditions is typically 200uA. An integrated charge pump is internally enabled only when the device is operating near dropout with low VIN. This ensured that the device meets the dropout specifications even for maximum load current and a VIN of -3.2V with only a modest increase in quiescent current. Quiescent current is always less than 350µA, with the charge pump enabled. Short-circuit current is internally limited. The device responds to a sustained overcurrent condition by turning off after a tON delay. The device then stays off for a period tOFF that is 40 times the tON delay.
