The LP2950 and LP2951 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 100mA) thus prolonging battery life. The quiescent current increases only slightly in dropout. The LP2950/LP2951 has positive transient protection up to 60V and can survive unregulated input transient up to 20V below ground.
The LP2950 and LP2951 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 LP2950 is offered in the 3-pin TO-92 package. LP2951 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 LP2951 also features the logic-compatible shutdown input which enables the regulator to be switched on and off.
The LP2951 device may be pin-strapped for a 5V, 3.3V, or 3V output, or programmed from 1.24V to 29V with an external pair of resistors.

The ALD1702/ALD1703 is a monolithic operational amplifier intended primarily for a wide range of analog applications in +5V single power supply and ±5V dual power supply systems as well as +4V to +12V battery operated systems. All device characteristics are specified for +5V single supply or ±2.5V dual supply systems. It is manufactured with Advanced Linear Devices' enhanced ACMOS silicon gate CMOS process.
The device is designed to offer a balanced trade-off of performance parameters providing a wide range of desired specifications. It offers the industry pin configuration of mA741 and ICL7611 types.
The ALD1702/ALD1703 has been developed specifically with the 5V single supply or ±2.5 dual supply user in mind. Several important characteristics of the device make many applications easy to implement for these supply voltages. First, the operational amplifier can operate with rail to rail input and output voltages. This feature allows numerous analog serial stages to be implemented without losing operating voltage margin. Secondly, the device was designed to accommodate mixed applications where digital and analog circuits may work off the same 5V power supply. Thirdly, the output stage can drive up to 400pF capacitive and 5KW resistive loads in non-inverting unity gain connection and double the capacitance in the inverting unity gain mode.
These features, coupled with extremely low input currents, high voltage gain, useful bandwidth of 1.5MHz, slew rate of 2.1V/ms, low power dissipation, low offset voltage and temperature drift, make the ALD1702/ALD1703 a truly versatile, user friendly, operational amplifier.
The ALD1702/ALD1703 is designed and fabricated with silicon gate CMOS technology, and offers 1pA typical input bias current. On-chip offset voltage trimming allows the device to be used without nulling in most applications. The device offers typical offset drift of less than 7mV/°C which eliminates many trim or temperature compensation circuits. For precision applications, the ALD1702 is designed to settle to 0.01% in 8ms.

General Description
The AAT2848 is a tri-mode charge pump optimized for systems operating with lithium-ion/polymer batteries. The charge pump provides power for both white LED backlight and flash, with an integrated four channel backlight LED current sink plus two channel flash LED current sinks.
Each backlight channel can drive up to 30mA, while each flash current sink/channel can drive up to 300mA (600mA total). Two independent S2Cwire™ (AnalogicTech’s Simple Serial Control™) serial digital interface inputs enable, disable, and set LED current to one of 32 levels for the backlight and to one of 16 levels for the flash, with fullscale current independently set for backlight and flash using external resistors.
The AAT2848 offers a built-in fade-in/out function for linear control of the backlight current during ON/OFF transitions. The fade time is programmable by an external capacitor.
The AAT2848 also offers a built-in flash timeout function as a safety feature associated with the high power flash driver. The safety timer is also programmable via an external capacitor.
The AAT2848 is equipped with built-in short-circuit and over-temperature protection. The soft-start circuitry prevents excessive inrush current at start-up and mode transitions. The AAT2848 is available in a Pb-free, space saving TQFN33-20 package and operates over the -40°C to +85°C ambient temperature range.

The AZ10/100LVEL16 is a differential receiver. The device is functionally equivalent to the E116 device with higher performance capabilities. With output transition times significantly faster than the E116, the LVEL16 is ideally suited for interfacing with high frequency sources.
The LVEL16 provides a VBB output for single-ended use or a DC bias reference for AC coupling to the device. For single-ended input applications, the VBB reference should be connected to one side of the D/D¯ differential input pair. The input signal is then fed to the other D/D¯ input. The VBB pin can support 1.5 mA sink/source current. When used, the VBB pin should be bypassed to ground via a 0.01 μF capacitor.
Under open input conditions internal input clamps will force the Q output LOW.
