GENERAL DESCRIPTION
The AMS2950 and AMS2951 are micropower voltage regulators ideally suited for use in battery-powered systems. These devices feature very low quiescent current (typ.75μA), and very low dropout voltage (typ.45mV at light loads and 380mV at 150mA) thus prolonging battery life. The quiescent current increases only slightly in dropout. The AMS2950/AMS2951 has positive transient protection up to 60V and can survive unregulated input transient up to 20V below ground.
The AMS2950 and AMS2951 were designed to include a tight initial tolerance (typ. 0.5%), excellent load and line regulation (typ. 0.05%), and a very low output voltage temperature coefficient, making these devices useful as a low-power voltage reference.
The AMS2950 is offered in the 3-pin TO-92 package. AMS2951 is available in 8-pin plastic SOIC and DIP packages and offers three major additional system features. An error flag output warns of a low output voltage, often due to failing batteries on input. The AMS2951 also features the logic-compatible shutdown input which enables the regulator to be switched on and off. The AMS2951 device may be pin-strapped for a 5.0V, 3.3V, 3.0V or 2.5 output, or programmed from 1.24V to 29V with an external pair of resistors.

DESCRIPTION
The TK715xx is a low dropout linear regulator housed in a small SOT23-3 package, rated at 400 mW. An internal PNP transistor is used to achieve a low dropout voltage of 105 mV (typ.) at 50 mA load current. This device offers high precision output voltage of ± 2.0 % or ± 60 mV. The TK715xx has a very low quiescent current of 25 μA (typ.) at no load. The low quiescent current and dropout voltage make this part ideal for battery powered applications. The internal reverse bias protection eliminates the requirement for a reverse voltage protection diode, saving cost and board space. The high 60 dB ripple rejection and low noise provide enhanced performance for critical applications.

FEATURES
*High Voltage Precision at ± 2.0% or ± 60 mV
*Very Low Quiescent Current
*Very Low Dropout Voltage
*Reverse Voltage Protection
*Miniature Package (SOT23-3)
*Short Circuit Protection
*High Ripple Rejection
*Can use Multilayer Ceramic Capacitors

APPLICATIONS
*Battery Powered Systems
*Cellular Telephones
*Pagers
*Personal Communications Equipment
*Portable Instrumentation
*Portable Consumer Equipment
*Radio Control Systems
*Toys
*Low Voltage Systems

GENERAL DESCRIPTION
TThhee AMS1082 series of adjustable and fixed voltage regulators are designed to provide 10A output current and to operate down to 1V input-to-output differential. The dropout voltage of the device is guaranteed maximum 1.5V at maximum output current, decreasing at lower load currents.
On-chip trimming adjusts the reference voltage to 1%. Current limit is also trimmed, minimizing the stress under overload conditions on both the regulator and power source circuitry.
The AMS1082 devices are pin compatible with older three-terminal regulators and are offered in 3 lead TO-220 package and 3 lead TO-263 (Plastic DD).

FEATURES
*Three Terminal Adjustable or Fixed 1.5V, 2.5V, 2.85V, 3.0V, 3.3V, 3.5V and 5.0V
*Output Current of 10A
*Operates Down to 1V Dropout
*Line Regulation: 0.015%
*Load Regulation: 0.1%
*TO-220 and TO-263 packages available

APPLICATIONS
*High Efficiency Linear Regulators
*Post Regulators for Switching Supplies
*Microprocessor Supply
*Battery Chargers
*Constant Current Regulators
*Notebook/Personal Computer Supplies
*Portable Instrumentation
