LP3991 Datasheet 300ma Linear Voltage Regulator

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: .. LP3991 300mA Linear Voltage Regulator for Digital Applications January 2007 LP3991 300mA Linear Voltage Regulator for Digital.

General Description

Operating from a minimum input voltage of 1.65V, the LP3991 regulator has been designed to provide fixed stable output voltages for load currents up to 300mA.

This device is suitable where accurate, low voltages are required from low input voltage sources and is therefore suitable for post regulation of switched mode regulators.

In such applications, significant improvements in performance and EMI can be realized, with little reduction in overall efficiency.

Key Features

  • Operation from 1.65V to 3.6V Input 1% accuracy at room temperature Output Voltage from 1.2V to 2.8V 125mV Dropout at 300mA load 50µA Quiescent Current at 1mA Load Inrush Current controlled to 600mA PSRR 65dB at 1kHz 100µs Start-Up time for 1.5V VOUT Stable with Ceramic Capacitors as small as 0402 Thermal-Overload and Short-Circuit Protection Package 4 pin micro SMD (0.963mm x 1.446mm) For other package options contact your NSC sales of.
