1FEATURES DESCRIPTIONThe LP38851-ADJisa high current, fast response
Adjustable VOUT Rangeof 0.80Vto 1.8V regulator which can maintain output voltage
• Wide VBIAS Supply Operating Rangeof 3.0Vto regulation with extremely low inputto output voltage
5.5V drop. Fabricated ona CMOS process, the device
Stable with10µF Ceramic Capacitors operates from two input voltages: VBIAS provides
voltage to drive the gate of the N-MOS power
• Dropout Voltageof 115 mV (Typical)at 800 mA transistor, while VIN is the input voltage which
Load Current supplies powerto the load. The useof an external
