| LT1680 Top sales Features . One mold small size package . Wide supply-voltage range : 2.7V t0 5.5V . Shielded against electrical field disturbance . High immunity against ambient light disturbances (Logic Controller Adaptation) . Available for carrier frequencies between 32.7KHz t0 56.9KHz . TTL and CMOS compatible LT1680 seller The LC35W256EM-10W and LC35W256ET-10W are asynchronous silicon-gate CMOS SRAMs with a 32768- word by 8-bit structure. These are full-CMOS devices with 6 transistors per memory cell, and feature ultralow- voltage operation, a low operating current drain, and an ultralow standby current. Control inputs include OE for fast memory access and CE for power saving and device selection. This makes these devices optimal for systems that require low power or battery backup, and makes LT1680 datasheet
LT1680 price The CS5257A-1 linear regulator has an absolute maximum specification of 6V for the voltage difference between VIN and VOUT. However, the IC may be used to regulate volt- ages in excess of 6V. The two main considerations in such a design are the sequencing of power supplies and short cir- cuit capability. Power supply sequencing should be such that the VCON- rROL supply is brought up coincidentally with or before the VPOWER supply. This allows the IC to begin charging the output capacitor as soon as the VPOWER to VOUT differential is large enough that the pass transistor conducts. As VPOW- ER increases, the pass transistor will remain in dropout, and current is passed to the load until VOUT is in regulation. Further increase in the supply voltage brings the pass tran- sistor out of dropout. In this manner, any output voltage less than 13V may be regulated, provided the VPOWER to Vour differentiaYis less than 6V. In the case where VCON- TROL and VPOWER are shorted, there is no theoreticallimit to the regulated voltage as long as the VPOWER to Vour dif- ferential of 6V is not exceeded. LT1680 pdf
