Description
The UCC384-x family of negative linear-series pass regulators is designed for low-dropout applications where low-quiescent power is crucial. Fabricated with BCDMOS technology, these regulators can pass 0.5 A while requiring only 0.2 V of input-voltage headroom. Dropout voltage decreases linearly with output current, resulting in a dropout of less than 20 mV at 50 mA.
Quiescent current consumption is typically 200 μA under normal (non-dropout) conditions. An integrated charge pump is enabled only when the device is operating near dropout with low VIN, ensuring that the dropout specifications are met even at maximum load current and a VIN of -3.2 V with a modest increase in quiescent current. Quiescent current remains below 350 μA with the charge pump enabled and does not increase with load current.
Short-circuit current is internally limited. The device responds to sustained overcurrent conditions by turning off after a ton delay. It then stays off for a period, tOFF, that is 40 times the ton delay. The device then begins pulsing on and off at a 2.5% duty cycle, drastically reducing power dissipation during short circuits. An external capacitor sets the on time, while the off time is always 40 times ton.
The UCCx84-x can be shut down to 45 μA (maximum) by pulling the SD/CT pin more positive than -0.7 V. For simpler interfacing, the SD/CT pin can be pulled up to 6 V above the ground pin without turning on clamping diodes.
Internal power dissipation is controlled by thermal-overload protection circuitry. Thermal shutdown occurs if the junction temperature exceeds 140°C, and the chip remains off until the temperature drops to 120°C.
