Description

The LP38842T-0.8 is one of the LP38842 series.The LP38842T-0.8 is a high current,fast respense regulator which can maintain output voltage regulation with minimum input to output voltage drop.Fabricated on a CMOS process,the device operates from two input voltage:Vbias provides voltage to drive the gate of the N-MOS power transistor,while vin is the input voltage which supplies power to the load.The use of an external bias rail allows the part to operate from ultra low vin voltages.

Features of the LP38842T-0.8 are:(1)ideal for conversion from 1.8V or 1.5V inputs; (2)designed for use with low ESR ceramic capacitors; (3)0.8V,1.2V and 1.5V standard voltage avaiable; (4)ultra low dropout voltage(75mV @0.8 A typ); (5)1.5%initial output accuracy ; (6)load regulation of 0.1%A(typical); (7)30nA quiescent current in shutdown (typical); (8)low ground pin current at all loads; (9)over temperature/over current protection; (10)available in 5 lead TO220 and TO263 packages; (11)-40 to 125 junction temperature range.

The absolute maximum ratings of the LP38842T-0.8 can be summarized as:(1)storage tempeature range:-65~150; (2)lead temp.(soldering,5 seconds):260; (3)ESD rating human body moder:2kV; (4)machine model:200V; (5)power dissipation:internally limited; (6)vin supply voltage:-0.3~6V; (7)vbias supply voltage:-0.3~7V; (8)shutdown input voltage:-0.3~7V; (9)lout:internally limited; (10)output voltage:-0.3~6V; (11)junction temperature:-40~150.If you want to know more information such as the electrical characteristics ,please download the datasheet in www.seekdatasheet.com .
