 peculiarity Ideal for conversion from 1.8V or 1.5V inputs Designed for use with low ESR ceramic capacitors 0.8V, 1.2V and 1.5V standard voltages Ultra-low dropout voltage (115mV@1.5A typical) 1.5% initial output accuracy Load regulation rate: 0.1%/(typical) 30nA (typical) quiescent current at downtime Low ground pin current under all load conditions Over-temperature/over-current protection Available in 5-lead TO220 and TO263 packages -40°C to +125°C junction temperature range   illustrate LP38842 is a high-current, fast response regulator that keeps the output voltage regulated with minimal input and output voltage drop. Manufactured using a CMOS process, the device consists of two input voltages: VBIAS provides the voltage to drive the gate of the N-MOS power transistor, and Vin is the input voltage, which is the load supply. The use of external bias rail allows for partial operation of ultra-low Vin voltages. With bipolar regulators, the CMOS architecture consumes very low quiescent current at any output load current. The result of using N-MOS power transistors with wide bandwidth but minimal external capacitance is the need to maintain loop stability. The fast transient response of these devices makes them suitable for DSP, microcontroller core voltage, and switch-mode power supply regulator power supply. The device is available in both TO-220 and TO-263 packages. Differential Voltage: 115 mV (typical) @ 1.5A load current. Quiescent Current: 30 mA (typical) at full load. Shutdown Current: 30 NA (typical) at S/D# pin at low level. Precision Output Voltage: 1.5% room temperature accuracy.   apply ASIC power supply: - Desktop computers, laptops and graphics cards, servers - Gaming set-top boxes, printers and copiers Server cores and I/O power supplies Power supplies for DSPs and FPGAs Postal Voltage Regulator for SMPS
