POWER MANAGEMENT
----------------------------------
* Low Dropout Regulators (LDOs):
The TPS721xx and TPS722xx families of low-Vin, cap-free LDOs are available
in fixed voltage (commonly used to power the latest DSPs and microcontrollers)
and adjustable options (ranging from 1.22 V to 5.25 V). They can be used
in applications ranging from portable, battery-powered equipment to PC
peripherals, and are particularly suited as a portable power supply solution
due to their minimal board space requirement and 1.8-V minimum input voltage.
Additionally, being able to use two off-the-shelf, AAA batteries simplifies
system design. They are fully internally compensated and use the load’s
existing 0.1-mF bypass capacitor to reduce component count and cost.

* High-Speed Amplifiers:
The THS4601 is a High-Speed, FET-input operational amplifier designed for
applications requiring wideband operation, high input impedance, and high
power supply voltages. By providing 180-MHz gain-bandwidth product, ±15-volt
supply operation, and 100-picoamp input bias current, the THS4601 is capable
of wideband transimpedance gain and large output signal swing simultaneously.
Low current and voltage noise allow amplification of extremely low-level
input signals while still maintaining a large signal-to-noise ratio.

* Special Functions for Amplifiers:
The LOG102 is a versatile integrated circuit that computes the logarithm or
log ratio of an input current relative to a reference current. The LOG102 is
tested over a wide dynamic range (6 decades) of input signals. In log ratio
applications, a signal current can be generated by a photodiode, and a
reference current from a resistor in series with a precision external voltage
reference. The LOG102 also features low supply voltages, excellent AC
stability, small package and two uncommitted op amps. Applications include
photodiode trans-impedance amps, ONET optical power measurement, and medical/
scientific instrumentation. It is available in a 14-pin SO package.

OPA655, it has significantly lower quiescent current and DC errors. The OPA656
(SO-8 package) is a drop-in replacement to the OPA655. It offers a wide, 400
MHz bandwidth, and high 290 V/us slew rate. It is particularly suited for
wideband trans-impedance applications (such as photodiodes), precision voltage
buffers and custom sample and hold applications. The output of the OPA656 has
adequate drive capability to easily drive doubly terminated 50-ohm transmission
lines or low impedance passive filters. Available in SOT23-5.
