LP3875ES-2.5/NOPB

TEXAS INSTRUMENTS  LP3875ES-2.5/NOPB  固定电压稳压器, LDO, 2.5V至7V, 380mV压差, 2.5V输出, 1.5A输出, TO-263-5

The LP387x series of fast ultra low-dropout linear regulators operate from a 2.5-V to 7-V input supply. Wide range of preset output voltage options are available. These ultra low-dropout linear regulators respond very quickly to step changes in load, which makes them suitable for low-voltage microprocessor applications. The LP3872 and LP3875 are developed on a CMOS process which allows low quiescent current operation independent of output load current. This CMOS process also allows the LP3872 and LP3875 to operate under extremely low dropout conditions.

**Dropout Voltage:** Ultra low-dropout voltage; typically 38 mV at 150-mA load current and 380 mV at 1.5-A load current.

**Ground Pin Current:** Typically 6 mA at 1.5-A load current.

**Shutdown Mode:** Typically 10-nA quiescent current when the SD pin is pulled low.

**ERROR Flag: **ERROR flag goes low when the output voltage drops 10% below nominal value LP3872 only.

**SENSE:** Sense pin improves regulation at remote loads LP3875 only.

**Precision Output Voltage:** Multiple output voltage options are available ranging from 1.8 V to 5 V with a specified accuracy of ±1.5% at room temperature, and ±3.0% over all conditions varying line, load, and temperature.
