DC432A
Analog Devices Inc.
The LTC1879 is a high efficiency monolithic synchronous buck regulator using a constant frequency, current mode architecture. Operating supply current is only 15?A with no load and drops to <1?A in shutdown. The input supply voltage range of 2.65V to 10V makes the LTC1879 ideally suited for both single and dual Li-Ion battery-powered applications. 100% duty cycle provides low dropout operation, extending battery life in portable systems.The switching frequency is internally set to 550kHz, allowing the use of small surface mount inductors and capacitors. For noise sensitive applications, the LTC1879 can be externally synchronized from 350kHz to 750kHz. Burst Mode operation is inhibited during synchronization or when the SYNC/MODE pin is pulled low.The internal synchronous rectifier switch increases efficiency and eliminates the need for an external Schottky diode. Low output voltages are easily supported with a 0.8V feedback reference voltage. The LTC1879 is available in a 16-lead SSOP package.Applications Cellular Telephones Portable Computers Wireless Modems

LT1964ES56 Demo Board | Negative Low Noise LDO Regulator, -2.3V ≤ VIN ≤ -20V, VOUT = -1.22V/-5V @ 200mA
Analog Devices Inc.
Demonstration circuit DC437 is a low noise negative micropower voltage regulator using the LT1964 low dropout linear regulator, which comes in a tiny 5-Pin SOT-23 package. The DC437 has an input voltage range from –2.3V to –20V, and is capable of delivering up to 200mA of output current. There are two circuits on this demo board: one uses the LT1964ES5-BYP which allows the internal reference to be bypassed to reduced output voltage noise, and the other uses the LT1964ES5-SD which has the shutdown feature. The output voltage is jumper-selectable and can be set to -1.22V, -5V or a user-determined value.
