Description : 1.425V to 3.6V Input, 1A, 0.2V Dropout LDO Regulators

General Description
The MAX8516/MAX8517/MAX8518 low-dropout linear Regulators operate from input voltages as low as 1.425V and are able to deliver up to 1A of continuous output current with a maximum dropout voltage of only 200mV. The output voltage can be set from 0.5V to (VIN - 0.2V) and is 1.4% accurate over load and line variations, from 0°C to +85°C.
These Regulators use small, 1µF ceramic input capacitors and 4.7µF ceramic output capacitors to deliver 1A output current. High bandwidth provides excellent transient response and limits the output voltage deviation to 45mV for a 20mA to 1A load step, with only a 4.7µF ceramic output capacitor, and the voltage deviations can be reduced further by increasing the output capacitor.

Features
♦ 1.425V to 3.6V Input Voltage Range
♦ Guaranteed 200mV Dropout at 1A Output Current
♦ ±1.4% Output Accuracy Over Load, Line, and Temperature (0°C to +85°C), ±0.6% Initial Accuracy
♦ Compatible with Ceramic Capacitors
♦ Fast Transient Response
♦ 320µA Operating Supply Current
♦ <25µA Shutdown Supply Current
♦ Short-Circuit Protection
♦ Thermal-Overload Protection
♦ Soft-Start Limits Inrush Current

Description : 1A Ultra Low LDO with Enable

General Description
The TS39105 are 1A ultra low dropout linear voltage Regulators that provide low voltage, high current output from an extremely small package. These Regulators offers extremely low dropout (typically 400mV at 1A) and very low ground current (typically 12mA at 1A). The TS39105 are fully protected against over current faults, reversed input polarity, reversed lead insertion, over temperature operation, positive and negative transient voltage spikes, logic level enable control and error flag which signals whenever the output falls out of regulation.
On the TS39105, the enable pin may be tied to Vin if it is not required for enable control.

Features
● Dropout voltage typically 0.4V @Io=1.0A
● Output Current up to 1A

Advanced Monolithic Systems Inc
Description : 1A VERY LOW DROPOUT VOLTAGE Regulators

GENERAL DESCRIPTION
The The AMS2501/AMS2502 series of adjustable and fixed low dropout voltage Regulators are designed to provide 1A output current. The dropout voltage of the device is 100mV at light loads and rising to 200mV at 500mA output current. A second input voltage of 1.2V or greater than the output is required to achieve this dropout. The AMS2501/AMS2502 can also be used as a single supply device by connecting pin1 and pin 8 together. In this case the dropout voltage will be typically 1.2V.
New features have been added to the AMS2501: a remote Sense pin is brought out virtually eliminating output voltage variations due to load changes. AMS2502 has an additional feature of an On/Off pin to keep the device in stand-by mode. The typical load regulation, measured at the Sense pin, for a load current step of 100mA to 1A is less than 1mV.

FEATURES
· Adjustable or Fixed Output 1.5V, 1.8V, 2.5V, 2.85V, 3.0V, 3.3V, 3.5V and 5.0V
